<< It's not because of me as his family members know that they have great differences in personality. He is destined to divorce with his wife as their hatred is very deep. However, their parents and my husband love the kids very much, hence his ex still had false hope on him when he went to visit them. >>
Now the "facts" have proved to you that they are not "destined" to divorce!! Your hubby now has shown to you "in action" that he misses his kids so much and his ex is still waiting!!
Having an ex-boyfriend and being his legal wife at this moment cannot exempt you from being a third party !! The ones who are innocent are only his ex, his kids of the ex, your ex-boyfriend and your own kid !!
The person your husband needed at that time when he had a bad relationship with his ex-wife was definitely a "social worker", and not "you" !! Do you understand ?
But now things have happened, by understanding the past, you should not have unrealistic expectation from your husband and his family (your mom-in-law) !!
