Ok, I meet the girl, She's seeing some guy who's married. I fall in love with the girl. We end up together. Three months into the relationship she fucks off to America 4 a year. We stay in touch 4 the whole time she's out there. We split up after about 2 or 3 months but stay in touch. It doesn't really feel like we've split. I go 2 see her last October and we get back together. She comes home 4 Christmas and it's Ok. I go 2 the States 4 a month and travel with her and we get on great and have the time of our lives. She comes home and after a week we split up! I feel fucking weird.
Basically, can we be friends? Can that really happen? That's what she wants. She wants me 2 promise that and I don't know if I can give her that 100% please post with advice. I don't want 2 tell 2 fuck off but 4 my sanity would that be best?
Advice would be welcome...

Sounds messy, but anyone can be friends if they want to be.

Go with your first instinct. Apart from that, be honest with yourself as to what type of relationship you really want to have with this girl. If she doesn't want a boy/girlfriend type of relationship, then it's not going to happen no matter how much you want it to. If you can handle just being friends, go for it. Please don't be offended but I would find it difficult to have or even expect a long term relationship with someone if I knew they had been seeing a married man prior to dating me.

I think this girl doesn't appreciate you and you should find someone who does. Sorry if it hurts you but it's the truth.

Prince articulated your situation the best in the song "Strange Relationship" I will give you advice that I learned from a real player.

1. Always reach your confort zone.

2. When in doubt "don't".

3. Be the easiest person to break up with.

4. Sometimes you got to jack off, back off, and get the
f%*! out

5. Never f.u.c.k. a friend.

if you both want to be friends, you'll be friends. if not, and both of you say that you want to be friends just to be polite, you'll drift apart pretty quickly.

F**K all that advice-you can't be friends with the girl without one of you wondering "what if..." -- one of you will secretly be wishing that it will lead to something more. BELIEVE ME. I'VE BEEN THERE (blame it on my hormones and lack of batteries for my dildo). Be careful---and watch when harry met sally-it's true-guys and girls can't JUST BE FRIENDS w/o one of them wishing for more...

Just listen to your the never lies.
