<human>: I have a problem that seems to keep recurring in my dating life. I start talking to someone on OKC or Tinder and we have good conversation and we seem to be into each other and then we hang out and its "you're really funny/nice/understanding BUT...." 

I'm not crazy and if this happened once or twice I wouldnt let it get to me but its now something that I almost expect to happen. I feel like when I'm just words on a screen i'm alluring to these girls but as soon as they meet me they lose all attraction. I have good pictures of myself online so its not like I'm deceiving them. I feel like because I'm not jacked or super manly or extremely tall, (i'm 5'9) they just lose all interest in me, If that makes any sense.

The worst part of all of this is I really click with these girls and if it was up to me I would have pursued relationships with so many people who have turned me down. I dont fault them at all for not being interested in me and we always part ways in a friendly manner but I am just so crushed and tired of being disappointed or feeling like a disappointment. I really just need advice or words of encouragement right now, thanks for reading my ramblings.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I click great with girls I meet online until they actually hang with me and lose interest. I feel like I'm not good enough and less of a man. What am I doing wrong?
