<human>: Can you provide a brief overview of the text?

Let me start this by saying I am very sheltered and do not understand a lot about relationships. I don't know how to act in one or what is normal or expected in one. 

Most of my relationships have been abusive from what I've been told by my friends, I don't know how to tell if one is a bad relationship or abusive, and I am confused about my current one as well as afraid it might be a bad relationship. One thing is, I don't know if I am her girlfriend. I was a year and a half ago in secret till she got a new girlfriend but a public one? It came out of the blue after she became less and less talkative.

Fast forward a few months later she asks for us to get together, we get together, we reciprocate mutual feelings of love, but she's still with the other girl possibly? But this time she didn't call me a girlfriend and I'm still secret. They hang out almost everyday and go out to eat and stuff, but her and I almost never do. I haven't seen her in three weeks. I understand she is busy with part time school and work, but I don't understand why, if we are in a relationship, that we don't go out or hang out?

When we do hang out though it's only for a few hours at most and generally something almost always comes up after she has sex with me. I just don't understand why. It makes me feel bad... Am I her girlfriend or not..? Is this a bad relationship- cause I feel bad..
<bot>: I don't know what I am to my significant other, our relationship makes me feel bad does that make it bad?
