I’m not sure if this is the correct place to post this but I need some help.

I’m 18/m. About 6 months ago I ended a relationship with my girlfriend. Long story short her family was crazy and she constantly depended on me and used me to feel secure.

She started dating someone, whom she often spoke about while we were dating, in just 2 weeks after we split . I spoke to her over the phone during the summer and she told me how this new guy is so much better than me and that he has done more her her in just 2 months than I did in 8. I spent so much money on her and had to deal with her crazy ass brother and it makes me feel like shit.

I struggle a lot with my confidence and self worth. I’m a 5’3-5’4 male. I’m 18 so I probably won’t be getting any taller. I feel worthless. She torpedoed my self confidence. I want to feel like a man. I’m the most grounded and realest person I know and I hate being this height I feel like a child. Since she said that to me I’ve invested 3,000 bucks and was able to get my own truck and figure out what college I’m going to attend. I’m proud of those achievements but I still can’t see myself as a man. I feel weak.

Anyone have any advice?
