Okay, so I'm gonna need you to actually listen to a stranger online....because at this point, me and many others on here, though strangers, are your fukking, life line. Firstly, don't worry about the c*nt girlfriend, we'll get to her in a minute. You need to find a reason to love yourself, because it seems like you're suffering from either, depression or some sort of childhood trauma. I would seek help. No, I'm not being funny, nor posting for likes on a forum. You need therapy, while in the process of getting it, you need to focus on yourself. Read, workout, eat meat, become a renaissance man or sorts. Stop looking for happiness from someone else who wouldn't understand true happiness if it flew inside their rotten cesspool of a vagina...
Speaking of your girlfriend, drop her. She's scumbag Stacy at this point and is literally bringing you down and manipulating you to the highest degree. She's a cancer, cut her off. Ask yourself "What would I miss if she left?" The answer sounds like it would be nothing, since she's not even willing to touch your dikk anymore. She's worthless, however she knows how to project that onto you and make you feel like you're the useless one. You're a man, show us all your radiance, because as of now, it just sounds like you're a void, null of any happiness and glory.
You're young, work on yourself, a good woman is a byproduct of great life well lived....not the goal, build a proper support group, love yourself as a man, but more importantly, as a human being. Stop being used by some soulless harpy who's more content in being a c*nt, than an actual lover. You need to steer your own ship, currently you're a buoy, floating behind her rust laden boat, desperately hoping for some sign that she'll pull you in....you're lost at sea kid, you gotta cut her off and get a little lost chasing excellence.
