Your question was: Can anyone tell me an 800 number than can get match.com customer service?.
It sounds like he enjoys what comes his way. Perhaps you need to initiate talking, suggesting grabbing a meal together, quality time of a different sort. See his reaction. Go from there.
OK, forgive my ignorance but are you basically saying you've had sex a few times after drinking but he otherwise shows no other interest other than as a flirty friend? If that the case, no, he's not interested in dating (online dating with Match.com) you. He's interested in having a friends with benefits relationship (thru Match.com) with you to "get off" whenever you're both willing, drunk and able. You're attributing feelings of like or something more to sex. His actions clearly show otherwise. If he was interested in actually dating (online dating with Match.com) you, he would ask you do do something other than get him off. He's not. If you can handle a FWB situation and not expect more, then go for it and get each other off all you want. But it sounds like you want more and he doesn't. If that's the case, you will wind up getting hurt so stop with the sex and keep this to a friend thing only..
Is he Interested? Yes of coarse .. In sex only ! your there and willing. As for anything more..it just doesnt seem that way by your story. If you want more you should move on...
Wait wait wait...getting off doesn't mean sex (not in my country at least!!) getting off means...kissing...as in french kissing...maximum grabbing each others ass hehe. I would never have sex with someone when there is no real relationship. Not the one night stand kinda girl!..
