I'm going to break up with my boyfriend because he is losing his hair
Why does him losing his hair bother you so much?
There are a ton of reasons. He looks like a monkey and I don't want someone like that.
It's important to be physically attracted to your partner, but it's generally not a good idea to break up with someone because of something out of their control. Your boyfriend isn't choosing to lose his hair so I think it would be best to try to be supportive!
It doesn't matter, I want someone better.
It's always best to try to be supportive and understanding of what your partner is going through. When you show kindness and empathy to others, they will return the same to you. Part of dating and relationships is learning to accept someone's flaws.
