<human>: I have a wonderful girlfriend who I really really like. We both have similar personalities, interests, and past experiences. She's a really kind girl, comprehensive, she's thoughtful and spiritual. She and I have told each other constantly that we want to grow together and that we accept each other with all our flaws. However, I still feel deeply insecure about myself. The reason is that I'm a 21 year old who doesn't have an university degree while she's 25 and has it. I feel like with me, she's going back in time instead of progressing, I feel that she should be with a person who also has a university degree, and can progress as much as she can. I also have deep insecurities about my physical appearance, I love her so much that I wish she was with a real handsome man, taller, more muscular, more energetic, with nicer facial features. I don't know, she has shown me her love but sometimes I can't help thinking that maybe she wishes she was with someone else too.
