I am sorry you feel so bad, but I can also understand why.
Loving someone that doesn’t reciprocate in the sam way is, to put it nicely, painful.
I lived my share of pain by having to deal with H’s family. They pushed me away and pulled H in, he was confused as to where his loyalty should be and that really hurt. I was tolerating it at first, I politely mentioned it, I got angry, than I went into apathy and the love I had for him slowly numbed.
Years later he recognized what they were doing, what was going on and that what I said about them was true, but it took a long time.
He changed, I changed. We are ok now, it was really bad for a while and each time he has to deal with them it gets him worked up and I end up with a mess at work and at home.
I hope he is seeing things for what they are more and more, but admittedly has a difficult situation.
What I don’t have to deal with anymore is a woman and her family stepping between us. If I had that I would definitely have to step away.
I had the ex wife and his and her family stepping between us and trying literally to cause a divorce.
I really do think it’s best that you focus on yourself and your family, rekindle your relationships with friends and change your focus away from them, away from him.
It seems like he is not willing to put in any boundaries and consequently hurting you, by keeping “his own family”, including the twin sister. It’s been 6 years and there is no excuse for doing it. At least my H did cut contact with exw and he brought me along to see his family. His mother even apologized to me in front of H, a few years before she passed. She wanted her son to know that she was wrong.
After she passed whole hell broke loose, because H wouldn’t obey his older siblings. His sister told me that he doesn’t love me and he will divorce me. That is how intensely they were working on breaking our relationship.
I think his deceased wife’s sister and family know exactly how to break you up all hoping they will succeed and that he will be free to build a romantic relationship with the twin.
I wish I could say you are wrong, but I think your feelings are spot on. It is just guilt that is causing him to at least inform you of what is going on and his children are the excuse they all use for extremely insensitive behavior.
If I were to guess, he needed someone outside her family to recover, now that he is recovered, just look who he is leaning to now, instead of going strong with you.
Again, I am sorry.
Stay strong and get a bit angry, not just sad. It’s easier to break away.
I am certain any good honest friend will tell you, you are right.
It’s not the end of the world. You can take your time and just stay away from him for a while. I would probably ask him to come over, tell him what is on my mind and just say, that is not how you treat your partner. That is not how you build a relationship. I would also be very honest and frank about the twin. If he would deny it, I would just say a woman knows when someone is trying to get involved in a relationship. It’s the respect for you they all lack and so does he.
Sometimes love is not enough, loyalty and respect are very key in a relationship.
