1) Do you think she's messing me about? For what it's worth I genuinely think that she's not that type of person, and she is just honestly conflicted, but I'm not sure.
2) Why am I getting so hung up on this?
3) What should I do if she decides she wants to get back with me?
4) Has anyone been in some similar situation and can you offer me any advice from experience?
1) I'd suggest that the ex/boyfriend is a "controller" if he has had a violent past and has hit her, it could be a possible fear of leaving him for fear of what he may do - maybe he's even blackmailing or threatening her.
You, as the sensitive, caring fun guy are the opposite - a safety net - one she can go too to feel wanted and comforted, almost a "holiday" from the norm.
Being in this position before i can tell you it will 90% lead to hurt. Generally Women who are abused and made to feel worthless tend to keep in that little niche, and getting out of it is something they are either unable to do - or too scared to try. - meaning she will likely stay with the abusee for fear of reprisal - coming to you periodically for some self worth before restarting the cycle.
2) Because you are a genuine, honest guy - you care for her, you want to make her feel happy. The thought of her staying with that Nincompoop (<- insert apt swear word) boils your blood. You can't help it, it may be how she wants you to feel, to keep you "on call" as it seems.
3) Tread carefully, outline what YOU want, or my guess she will go back with the ex/boyfriend. My guess is, if you tell her you want no commitment she will go back to him - if she doesn't perhaps it is genuine that she wants to be with you - other wise its the safety net thing again.
4) Yes, it involved alot of heartache and me joining the Navy to get away from it all! (not females....... ;D) I had a 3) happen, she was still with the abusee and eventully left me again for him. However my "leaving for the forces drink" did, as fate had it lead me to a pub he they where drinking at the time. His smile is a lot less pretty now!
If you have even the slightest feeling you are going to be hurt, i'd say stay away. But as i thought at the time, whats a burn, if not a realy cool scar!
I kinda wish i hadn't now.
Hope this helps
