This may be long so forgive me. I really do not know what to do about this, and i'm hopefull someone out there has some good advise.
I split with my dh around 13 years ago. We have 2dc. He had a short other relationship after we split and then about 7 years ago we got back together (his relationship had finished). But we always ended up arguing. In short, we just shouldn't be together. 3 years ago we split again, this time for good and got a divorce.
Our 2 dc lived predominantly with ex dh since the initial split, mainly because of location to their friends/work/school etc. And I was the main earner at the time and worked alot. The dc are 29 and 34, and the 29 now lives with his dad.
Around 6 months after this split I met someone through a mutual friend and we really hit it off. It turned into a relationship, we live together and plan on getting married.
However. My dc are refusing to visit, will have nothing to do with new dp, will not see me if he is with me. Their reason is because I should have stayed with their father, not got into new relationship so soon. New dp has 1 dc, who is 15 and lives with us. My dc hate this fact and won't have anything to do with him because they say I shouldn't be a parent to him.
They have both now issued an ultimatum, in that they will see me as long as dp not there or they will refuse to see me at all if I can't accept this.
DP is pretty hurt by all this, quite rightly so, and I am embarrassed by their behaviour. AIBU to call their bluff and say no, I am happy and you need to grow the hell up and accept it. Or do I do what they say and effectively dismiss dp and step ds from my life when I see my dc as though they do not exist? I will find this very hard to do but I don't want to lose contact with them, as at end of the day they are my dc.
Really could use some advice how to best deal with this.
