I'm 18, my girlfriend is 16. My girlfriend says she needs a break to "focus on school and family" but "we will get back together in the summer, or until I can't stand being without you." She says she loves me, and that I'm her first real, and longest relationship. I've tried talking to her about it, but she just gets mad. When we text, she only used 1-5 word replies, and when I ask her to talk more, she just says sorry, and doesn't do anything about it. Because of all this, I don't know if I still love her. I keep having mixed feelings, one minute I want to fight for her, but then the next I want to end it. I'm thinking about going "No contact" and see how that works. I'm so confused!

I forgot to mention, that when we first started dating, she loved kisses, and made me get MSN so we could video chat every night, but about a month ago, she doesn't like kissing anymore, and always says no when I ask her if she wants to get on MSN

Sounds more like she's given up on the relationship and just giving you excuses. Do you really want her to bluntly say that she has no more feelings for you?

Why continue a relationship with someone who doesn't even care about you anymore?

I think she is having doubts about the relationship. Or she could just be emotionaly unavailable, for whatever reason? If she mad it clear she wants to take a break (meaning break-up for a while?) then don't wait around to get your heart broken, explore your options too and date or hang out with other people. Then you will have a clear understanding if you really want to be with her or not :)
