Yes, I have recently reconciled with my semi-estranged daughter, although she is still not in contact with her sisters.
It is a difficult path to travel. She ceased contact entirely for six months, although she did send birthday cards etc. She moved house without giving us her address, got married without telling us for over a year, and gave birth to DGD1, but didn't tell us for 14 months.
The pain runs very deep and I feel all of that anger and hurt and, yes, jealousy, as she shared all of these things with her in-laws and not with us (although I am genuinely pleased that her in-laws have been supportive). However, I am trying very hard to be positive and, as my husband has recently been diagnosed with an aggressive form of cancer, this puts things in perspective.
I know that I have to move forward, the past cannot be changed, and what is the alternative? My daughter is genuinely making a big effort, frequent calls, messages, pictures of DGDs, enquiring after DH. home made cards etc. She can do no more, I know that. Sometimes, it is so hard not to say to her - don't you realise the pain you have caused, and the damage you have done - but what good will it do? As others have said, it will make her uncomfortable and therefore there will be less chance of further improvement in the relationship. She will be defensive and lash out. So I try to switch off and detach, sit on my hands, don't message when I am angry, and note that if I convey positive messages, I receive positive messages back. And that makes me happier - it is a gradual process, but it is better than anger. Baby steps and all that...
Our estrangement was also caused by a third party, her then boyfriend, now her DH/my SIL, whom I believed to be controlling. I intervened when I thought he was bullying her. It was a big mistake, but I am not sure that I could have made a different decision, even with the benefit of hindsight. In the end, whatever the hurt and the pride and especially the fear, you have to let love win through. Life is too short to do anything else. Sometimes - often - you need to take the risk.
@Jenny - I would advise you to please take that risk, although the results may not be instant. Plant a seed, and it may grow into something big and strong and magnificent. Don't give up. Children are hard-wired to love their parents, but families can be very difficult, and sometimes you need to step back a little and have patience but, above all, unconditional love. Good luck!
