My boyfriend (35 M) keeps ignoring me (31 F) on weekends and going to hang out with his friends (all men) instead of spending time with me. Is this normal?

My boyfriend and I have been dating for several years. In recent times, he started to ignore me more often, especially on weekends. During these times, he would go and hang out with his friends who I have never met. He always tells me that he only hangs out with his guy friends, and he never allows me to accompany him. He claims that his guy friends prefer to spend time with just men and don't want to hang out with their wives or girlfriends around.<br>He recently told me that he didn't want to spend all his free time with me. He wanted to have time for himself and time with his guy friends. I've never been in a relationship where the man prefers spending time with men only and I'm not familiar with this type of friendship. To me, it feels like he doesn't want to spend time with me because I'm a woman. The distance between us has grown dramatically since he started ignoring me and it's affecting our relationship. Also, I think it's very disrespectful to say that all his friends don't want to hang out with women, it makes me feel like he sees me as inferior.<br><br>Should I address this issue with him or ignore it and let him choose what he wants to do? Am I wrong for feeling like I'm being discriminated against with him?
