How do I stop feeling like why would anyone love me? (that’d something that I constantly think to myself)?

Maybe it could be because I notice that I’m never approached by anyone meanwhile everyone has their own group? I find it hard to believe though that someone could love me and I am in a relationship right now that’s been more than a year now. I don’t know why I question so much why would someone love me. Also how do I love myself? I’m very shy and awkward and sometimes I accept my personality but other times when I’m with my boyfriend’s family i worry that they won’t like me and think that I’m weird because I’m so shy and can’t make eye contact. On top of this my boyfriend has given me a promise ring and told me that he wants to marry me so many times but inside my head I think “why would someone want to marry me?” And i don’t know i just feel like maybe he just felt lonely I don’t know any other reason why someone would would love me. I’m very affectionate but what else do I have to offer beside that and me having this full time job?
