My girlfriend of 3 years and I broke up 3 months ago now. I've been trying to get out there and atleast get laid. However...I seem to keep running into the same scenario where I fail to close. I'll break it down with some recent examples.

The Nurse

I've worked with this woman for a few months, but recently started becoming friendly. I posted on Facebook about wanting to go camping and she said she wanted to come. She gives me her number and starts texting me like crazy. One night I get off work to an invite from her to go to the bar with some other coworkers. I go, and she is engaging me repeatedly, and seems to show interest. I make a move and put my hand on her thigh. She takes my hand in hers and we continue flirting and talking. Shortly after that the bar closes and her male friend/dd cock blocks me into not getting in the back seat with her on the way back home. She keeps holding my hand and rubbing my shoulder the whole ride to my place. I invite her to come in, but the friend puts the nix on it. 10 minutes later she's texting me, reassuring me that I don't have to worry about the friend, because he's like her brother. Seemed like a pretty clear interest. After that, she acts like it never happened, and I haven't been able to even hang out with her since. I asked her out, twice, and got the typical indirect girl rejection, so I moved on.

The Friend of the Sister

Known this girl for a few months too. Hit the bars together a couple of times. Really flirty and physical. One night she invites me out to the bar, we have a good time and go to her friend's house. I escalate physically, and she's responsive, and we end up making out. She admits to me that she's had a crush on me for months. I attempted to F-close, but she didn't want to because we were sleeping in her friend's living room. Couldn't break through the resistance. Drive her to her car in the morning and we kiss goodbye. Ask her out twice, and get the "I work early in the morning" excuse both times. I move on.

The Seemingly Innocent One

Worked with this girl too. She was leaving the job for a better opportunity and we threw a big going away gig for her at a bar. She gets drunk and crazy. Makes out with me and gives me a lap dance. Rubs my junk through my pants. Seemed like a slam dunk, but once we get to her place, she freezes me out, and I end up sleeping on the couch alone. All attempts to see her again have gone unanswered.

It's kinda frustrating. Things seem to be going well, but then I hit a dead end. Tempted to call up the ex to try and rekindle things because atleast I know she'll reciprocate, but I know that's not a good idea.

Any advice??
