I looked at a few guys today and I cried
Why do you cry if you look at a few guys?
They seemed to be better than my boyfriend
If you feel unhappy with your relationship you should talk to someone about it. It is also not ok to look at other people when you are already in a relationship.
Why not fuck those guys then?
I think if you are feeling depressed about this you should not ignore those feelings. You shouldn't have to feel trapped in a relationship if you don't want to be.
