Hi Fresh Prince!
Sounds like you were in a dyfunctional and even co-dependent relationship.
It worries me when, after all you have written you conclude with:
Anyway, I don't know what more to say. I feel like I may end up going back to her, even though I know how unhappy I was in the relationship, especially over the past year. But the guilt and anguish I'm experiencing over leaving her is just too much.
WOW! Dude! Be strong!
Sometimes when you are in a relationship like this its like being inside a long dark tunnel. No, I am not going to tell you to look for the light at the end of the tunnel, you need to crawl out of the tunnel man!
Functional, happy, equal relationships do exist- and you could even have one! Dont let her low expectations affect yours. Climb out into the fresh Ohio air!
Maybe this lady will be alright, and maybe she wont. She may self destruct but I hope she doesnt. In any case staying with someone to prevent an implosion is not a good solution.
Cut her off- no phone calls, texts, or emails. Be strong and stoic like the Marlboro man and walk off into the sunset.
