Dad had another family...

nana8 has given you sound advice.
I do agree that counciling would be a good idea and i would really try to find your sibling as they may feel exactly as you do .
And tbh,i think your mom should talk to you about it as i would feel betrayed by both parents.
Sadly you are not the first to find things like this out and you won`t be the last either.

Big virtual hugs Polarbear. I can’t really add to what others have said, but agree with Iam64 that it’s best to wait awhile before deciding what, if anything, you want to do about this.
Yes you must feel betrayed and confused - but your father loved you and that’s something to hold on to.
Remember that if indeed you have a half-sibling, revealing your father’s double life to them could be as shattering and confusing as it has been for you.
I do wonder about the motives of the ‘friend’ who enlightened you. It’s hard to think that kindness was behind it.

Don’t know how old your mum is but if you’re mid 60s your mum maybe mid 80 s and you could be waiting 10/15 year??? but to be honest there’s nothing you need to do tuck it to the back of your mind and get on with life once you’re over the shock, after all it wasn’t your secret was it ? and obviously Mum came to terms with it or else she would have left your Dad and there’s nothing to suggest he was a bad man or a bad Dad just different to what you knew doesn’t necessarily make him bad though
Many men have children outside their marriage and never support them they just get out and forget it happened it seems your dad supported two houses

I d want to find my half sibling though

I’d thought I should wait til mum dies before saying or doing anything? She can’t have too much time left. Thought it’d be kinder???

Personally I would go back to the "friend" who told you and see what else they can tell you. I don't think you should press your mother for further information, it must have been a terrible shock for her that you suddenly knew all. Certainly a chat to somebody may help you get things straight in your own mind, I do hope so.

Thanks all. Just been to see mum. She’s all relaxed and smiling now. I didn’t say anything. She doesn’t need any more drama. OH just said ‘what’s up with you’ because I looked sad. He thinks it’s nothing to bother about. Now previously I’d have thought it must be me over reacting but I’m not allowing that. My feelings are genuine. I must be improving in my old age.

Please do as you've suggested yourself and see a counsellor. It must have been very upsetting and unnerving to be told that by your Mother out of the blue, especially as you have lost a sibling previously. Sit down with a counsellor and talk it through and see what you may or may not want out of this information first. You also have to prepare yourself that it isn't just about your wants and needs either, if you do want to pursue it further, other people may not feel the same which is why it is important for you to have support through this.
I hope you are ok

I wouldn’t judge without knowing all the facts, you don’t really know the circumstances of your parents marriage, no child can.
I feel my dad probably had a very lonely and unfulfilled life with my mother, I can’t imagine what they ever saw in each other.
Personally, it would make me very happy to uncover a double life if I felt he’d derived some happiness from it.
I know your circumstances are different, and I’m not suggesting your parents weren’t happy, but you will never really know.

I can understand you being extremely disappointed in your father but the rest of the family had to go along with your mother’s wishes. I would assume she tolerated the situation to try to give her children a normal life. Just think of the agony she went through.
If you have a half sibling/s wouldn’t that be wonderful. They would be innocent parties in this charade so no need to feel animosity towards them.
I think your mother needs to be supported and hopefully she might open up to you.
Please don’t let it spoil your life. Your mum and dad loved you. I suggest you speak to your aunt/uncle and tell them you know and would like their help in locating any siblings but wait until you can be less emotional.

Yes I would definitely have some counselling to get it all sorted in your head and be able to come to terms with this new situation I m sure your mum and dad kept you out of the loop believing it was for everyone’s sake, not as a direct lie , but to preserve the family dynamics, your mum out of loyalty and your dad out of preservation
It is hidden problem that is more common than most people believe
Your mum must have loved your dad very much if she stayed whilst knowing this and you were brought up in love and obviously had a good childhood, it’s been a shock for now and the keeping you in the dark is probably what’s hurting more than anything else, hopefully you will come to terms with this information in the future and perhaps be able to find and meet this half sibling and enjoy a relationship. It’s not their fault any more than it’s yours
Hopefully your Dad supported both families and it really doesn’t alter the love and care they gave you and your sibling it wasn’t done behind your mums back
And yes I do have experience (not my Dad, bless him ) which I won’t go into on here

This is horrible betrayal
Now that the secret is out, there is no win win

If you dont ask your aunt and uncle, you will wonder if they knew

If you ask and they knew, feelings are understandably hurt

What else your family may hide, I would wonder.

I would look for the sibling if you are interested and cut off the middleman.

I’m inclined to think counselling may be helpful. Discovering a family secret of this magnitude is clearly not easy for you to cope with on your own.

Nothing has actually changed. The only difference is that you know something you didn’t know before, and it has altered your view of the people involved. You can’t change the past, or what people have said or done since. What you can do is work through why it matters so much to you, and learn to re-organise your thinking so that you are no longer angry, hurt and sad.

Angry, sad, hurt - the only advice that comes to me mind,is to sit with those feelings for a while. Meanwhile, yes as you suggest some form of talking therapy is a good idea. Don’t rush off trying to track down relatives till your own feelings are less raw. Look after yourself xx

nanna8 Completely agree with everything you’ve said.

If they had a child you have a half brother or sister somewhere. Personally I would want to meet them and try to find them. It is not their fault and they might be pleased to find a close family member - and so might you after the dust settles !
