@Guest11,
Hi Guest,
I'll try to be as sensitive as I can to the situation OP is facing. Divorce is never easy. There's no set rules one must follow to ensure life after divorce will be happier and more meaningful than it was while married. Having said that, there are multiple red flags here. To ignore them sets up the relationship for failure.
Compromise is a nice concept but that isn't what OP is after. To her, compromise means bio mom loses out on family functions that includes her own daughter and step mom takes over. Right there, is a source of contention. Yes, I am divorced and remarried, so yes, I do know what I'm talking about.
Here are the red flags from the OP's post:
-We have one big problem though... and this problem is not letting me to be completely happy with my man...
There's always going to be rough patches where Happiness will not always be present.
-he and his family decided to keep his ex included in the family.
Hey, it works for them.
-In my culture it is not normal to have two women of the same man to be at the same place sitting across the table and hanging out together.
Well, in his culture, it is.
-while being sympathetic to my feelings, he says that he can’t do anything about the situation as his ex will always be his child’s mother and she will always be included in his family gatherings.
An appropriate response in a divorce situation.
-His mother is not willing to understand. She said that I am a big girl and have to pull up my big girls panties and just do it...
Healthy relationships includes boundaries, this one is his mom's.
-- I feel that if he continues going there without me, it will draw the wedge between him and myself and will not help to continue building healthy relationship between us...
That seems reasonable.
- I was talking to my fiancé about it and convinced that we need to explain meaning of divorce to his daughter and that now she will have two families - one is her mother and her and the other that includes her father (my fiancée), me and both of our daughters.
This is wrong on so many levels it would take pages to explain.
-Talking direct to his ex about the situation is out of question. She has a temper and has tendency to twist everything that has been said to her (based on my experience)
Yes, I wouldn't act nicely if a proposed step mom tried to come between me and my child.
This is the reason why healing after divorce is crucial. OP doesn't see these red flags, or at least minimizes how contentious they actually are. There's no compromise in certain situations. It just is. Again, I see no upside to what OP is doing. It's best to back out gracefully and find someone else who doesn't have small children to consider.
