I've attracted some incredibly beautiful and well-rounded women before. I've had a few flirt with me while we were friends and theres this one woman who wont stop looking at me in the gym. The only problem is, whenever I catch on that they are into me I fail to escalate further because of my low self-esteem. It usually always end up the same way. I keep treating them like a bro until they eventually lose interest. I'm going thru a cycle with another friend rn and I think she's also done with me. I'm not very well versed in flirting, because I grew up with barely any romantic interest from women. So whenever they flirt with me I feel like they're just toying with me and I end up pushing them away. I want to stop this cycle and eventually escalate into a relationship. Any advice on how to work on this?
