It's neither my passion nor my mission to help single men be better, except to point out to them how the social system of patriarchy is screwing them over as well. That doesn't mean that I don't have sympathy. That is the honest truth. Although I don't know anything about you other than what I've gleaned from our few exchanges, I feel like you are someone who is in a lot of pain, which doesn't bring me any joy.
There are all shapes and sizes of men out there who have partners. It has more to do with what's inside than what's outside. I took a look at your profile image and you are a nice looking guy, so you do have that going for you. I think you just need to find a way to heal your wounds, which I realize is a tall order. Yes, therapy costs money but there are books and on-line resources out there. I'd recommend things related to shamanic healing, which can be incredibly helpful in a much shorter period of time than years of therapy.
"When we experience something upsetting or traumatic, a part of our essential self dissociates or fragments off as a survival mechanism. This is referred to in shamanic circles as soul loss.
The types of trauma that could cause soul loss in our culture would be any kind of abuse sexual, physical, or emotional. Other causes could be an accident, being in a war, being a victim of a terrorist act, acting against our morals, being in a natural disaster (a fire, hurricane, earthquake, tornado, etc.), surgery, addictions, divorce, or death of a loved one."
Take care. I wish I had more to offer you.
