Hey all. So my live-in LTR (yes I fucked up) and I have been together for about a year. She took care of me when I was quite ill for months so I feel some sense of loyalty to her.

In attempt not to hamster, this girl is great. Good body, attractive, sweet. She's got some clingy / jealousy issues but those are things I can work through. The thing I can't work through (and never have been able to) is that no matter how much I care about the girl and how much I like having her around ....

I am obsessed with fucking other girls.

Am I (or all men) destined for this curse no matter the girl they are with?

I am struggling with whether to break up with her right now and the sole reason would be so I could get out there and fuck other hot girls.

About 3-6 months in to any relationship this happens. In some ways it seems so petty and lame that I desire validation / sex from hot girls so much that I would blow up an otherwise decent LTR just for that, but that's where I am.

I have a large sense of unfinished business and wasted time because my high school / college years were spent being a repulsive outcast.

Is this something I can fix? Should it be fixed?

[EDIT] I also dread "hurting" this girl as she has done a lot to be a good / better partner to me. I hate thought of her emotional devastation if / when i end it. It's super codependent but that's how I've always been. I can't stand to see the look of panic and confusion on a girls face when I tell her it's done.
