I get upset with my boyfriend really, really easily?

I'm only 15, but me and my boyfriend have been together for a while. He can be the same way with hanging out. I wouldn't take it seriously if that's just the way he is. But, he probably doesn't realize he's hurting you. If it really bothers you I'd just mention it to him without sounding clingy and all. I'm sure you really like him or love him and that's why you feel this way. I understand how you feel though.
