I have ruined my husband’s relationship with his family because of my own selfish feelings

This may be a long post, so bear with me. My husband has always been super close with his family, even though he’s always lived an hour away from them. Before he met me, he was going to see them 3 or 4 times a week after work. He babysat his nephews, took them trick or treating, Easter egg hunting, ran every birthday party, and made every program they ever had. He was close with his sister in law and sister (who live right by eachother), and did everything with them. When we started dating, that somewhat stopped. Not because I asked him to, but I guess he had other things to do with his time. I lived closer than his family and started occupying his time more.

Unfortunately, as we were dating, his family never took the time to get to know me. We went to visit them quite a bit but they always shunned me. I would be the one making conversation and trying to essentially gain their approval. We got married after 9 months together and things got even worse. They showed their asses at our wedding. We have been married since August and that still hasn’t changed. They barely speak to us now and he barely talks to them. I have let the fact that they were so rude to me for so long make me bitter and I think he feels he has to choose between me and his family and I don’t want that. For so long they were his source of happiness and now he barely even sees them because of me.

Last week his sister finally sat us down (this was a rare occasion when we got a invite over, and this talk was why she invited us), and told us they don’t see him enough. I was sitting there the whole time and she never mentioned getting to know me even though he kept bringing it up that they know nothing of how wife. She then proceeded to say that her, their brother, and the sister in law all had discussed it and felt that He couldn’t be himself since he married me. She said it as if I wasn’t even sitting there. It really hurt my feelings because now I feel like maybe I have changed him for the worse and didn’t even mean to... I’m 5 months pregnant and so stressed with the drama and I feel like the worlds worst wife and I don’t know how to make it better.
