 So i have this girlfriend. She's great. A little on the crazy side but we are working on it.  I have this ex and she's a little on the crazy side too but she's working on it.  They both love me...ALOT. So i feel so guilty.  I have so many unresolved issues with my ex and part of me still wants her. She was my first love, i don't think ill ever be completely over her.  A life without my ex in it seems so unreal to me.  We were together for 3 years.  Now my current girlfriend lives 5 states away -___-.  I love her i really do but when i picture my future as much as i want her in it, i just don't really see her with me.  I feel like she loves me way more then i am capable of loving her.
This situation makes me feel like a complete bitch.  I have two girls that love me and i'm still saying poor me. I don't mean to though.  I just am really at a loss of what to do.  I haven't been legit single for almost 5 years.  Now i'm only 19. that is a really long time to not be single.  I feel like i just need time to myself to figure out everything in my head. To be able to just make decisions and not have someone else affected by it.  I don't really know what to do.  No matter what i decide i will end up breaking someone's heart.  I have been in this situation for a couple months. I have to do something about it, i know this. I just am so scared of doing the wrong thing that i can't even decide what i truly want.  help?! :/
