Obviously I don't know you and I don't know your life story, but I have also recently been dumped, days ago. I'm also questioning what I have to offer to anyone, or whether I'm missing some kind of internal spark or piece of humanity. Every person I've had a relationship with has said "You're a really lovely guy, you don't deserve this, you're the best person I've ever met, you're kind and generous, and thoughtful and loving..." and yet somehow it isn't enough. I do everything that I see women on here wanting in their partners - I do the housework, I'm affectionate, I don't pester for sex, I praise them and make them tea and blah blah blah everything else I can think of to demonstrate my love for someone, and yet.... nothing.
I'm starting to feel like I'm just missing something intangible that makes a spark with another person. I don't know.
However I do know that having a partner is an optional extra - not a reason for existence. If I spend the rest of my life doing what I want to do, and learning new things, and having fun, and visiting new places, then that is a life that was worth living, and Hollywood can fuck RIGHT off if it tries to tell me otherwise. Do I want love? Yes. Do I want a good relationship? Yes. But am I a failure/unlovable/doomed if I don't have those? Fuck no. I am Sethis. And I am a person. I have a life. I have the right to happiness however I can find it.
You can't do anything about old.
You can do something about mental baggage.
You can do something about your weight.
You can do something about being untidy.
Now I'm not perfect. I'm a little flabbier than I'd like, because where I live at the moment there's no facilities for me to lose weight. But after being dumped, I've gotten a haircut and I'm going to make sure I dress as sharply as I can on a day to day basis. Partly to try to attract another woman, but also partly because it's important to my sense of self. I'm lucky not to have too much mental baggage, and I don't do pep talks, but the guiding principle of my thoughts on this is "Baggage only weighs you down so long as you choose to carry it." That may or may not be helpful to you right now. In any case, I do hope you can move forward and keep in mind that you do, in fact, have inherent value.
