I met this girl and we are both in the military. I'm 19 she's 22 and we met because we share similar problems from our past. She has a boyfriend but the only reason why she is with him is because she wants to stay in the safe zone so she doesn't get hurt. We both told each other we have strong feelings for each other. But the only thing stopping her and she feels bad for her boyfriend because he treats her right but he can't relate or understand her the way I do because he's never had a hard past. Her and I came to the conclusion that we couldn't keep kissing because she has a boyfriend and she feels bad because he's a good guy. She told me that most of her relationships last about three months they've been together for 2 months. Recently she told me even though we couldn't keep hooking up she still wanted to see me in her life but I said I can't either me or him. She misses me a lot and is sad but I can hold a grudge. What do I do?
