Hi Toe Toe.
I'm glad that you have decided to accept the olive branch and I wish you will. I think you have done the right thing, I agree you will need to tread warily but at least you will be able to slit any warning signs, but you have got over the worst.
I had similar issues to you last year......
I completely backed off (using what I call my red rope policy) and waited to see what happened. Eventually it paid off and my son offered an olive branch which I accepted, with grace, dignity and charm,
My thoughts are........everyone deserves a second chance, but there won't be a third. I haven't voiced tgat to my son, but he knows me well enough to know I mean business. He knows he's lucky I took him back and I doubt very much he will risk it again. I believe my son is genuinely contrite and full of remorse, I haven't had an apology and I wont push for one,
I know I might sound a bit controversial here but I disagree with your sister. I did not push for explanations or try to "thrash things out". I don't think post mortems in these cases are all that helpful. I think it's better to let sleeping dogs lie.
Your daughter made the first move, and that takes guts. Without saying a word, she has admitted she was wrong and has demonstrated a willingness to make amends. If I were you I would take a keep of faith and accept her back with open arms,
I know that for some people that wouldn't be enough, they would insist on apologies and explanations. Maybe one day she will open up to you and you will get a fulsome apology and a full explanation of what went wrong but I think it's perhaps a bit too soon. The reconciliation is in its early stages and probably quite fragile so maybe better not to push too hard.
I can appreciate you want answers but if I were you I would just take her attempts at reengaging at face value. Maybe just give her the benefit of the doubt for now and adopt a wait and see approach, that's what I have done,
I think we sometimes need to ask ourselves......"Do I want to be happy or do I need to be right".
For myself I have deliberately chosen happiness, re-engaging with my son and being able to have a proper relationship with my grandchildren.
I know not everyone shares my view, maybe some people might find me foolish. I do agree wholeheartedly that once our trust has been betrayed then it's very difficult to completely relax and let go and trust again. I think I will never be able to fully relax with my son ever again, I will always be guarded and careful. The happy go lucky relationship we had is gone and I doubt very much that it will ever be quite the same again. It will do. It is what it is. It's warm and cordial. I am still quite reserved and careful (especially with DIL). I play the long game and keep my cards close to my chest.
I was speaking to a friend yesterday who had been estranged from her daughter for 3 years and then suddenly, out of the blue, her daughter asked for a meeting, I asked my friend if they had "thrashed things out" and she said no. She felt, like I do, that it might have been counter productive to insist on a post mortem. Like me she just accepted her Daughter back into the fold and left it that.
Anyway that's my take.
Only you can decide what's best for you but I would advise you not to be too hasty, just take things slowly, protect your self but try to find it in your heart to forgive. (But not forget, stay on your guard). If that's not possible then just accept the olive branch and wait and see.
Bearing a grudge serves no real purpose. Holding on to the hurt and pain was making me ill so I decided to let it go. I am nearly 72 and I chose not to waste my time with recriminations and playing the blame game.
My mantra is......
"Life is short.......take the trip, buy the shoes, eat the cake and above all, don't let arguments fester and destroy what time I have left".
