Resentment towards Friends

Hi all. Really just looking for some advice to work through some feelings I have about my college roommates. We lived together for the past three years but we are all in different states now. We try to keep up via online chats but I’ve found that I recently am dreading these conversations.

Because of the undergraduate school we went to, all four of us lived in a small room and were sometimes confined to this space only for a couple weeks due to COVID. In some ways, this lead to us being closer but also seemed to create tension for me. I always feel left out because my values are different than theirs. I find it hard to share things about my myself because they always seem to misinterpret what I am saying. For example, one we were talking about characteristics of people we would date since only one of us did not have a bf at the time. This was when I was with my ex. Everybody was sharing and when I said I could date someone taller, they immediately started to suggest that I was leading my boyfriend on if I was saying that. I personally believe that not all relationships end in marriage but they believe that they date to marry. I responded that I wasn’t sure about marriage, and I felt bad about my responses and who I was. There are other instances where I feel that I am too different. Recently, I confided in one of them that I was questioning my sexuality. They were supportive but they sent me a letter that they were questioning too and that they weren’t copying me and that they hope I wasn’t mad. This made me feel really bad that I gave off that impression. I do take pride in being independent and an individual, especially since I value my time alone as an introvert. I am harboring a lot of resentment and I would appreciate any advice on this topic.
