TL:DR: Plate confirms for me that my instincts were correct and I need to remember that what all signs point to is generally true.

Body:

My main plate at this point I've been dating for about two months. At the very start (after about four dates) she left to go on a trip down south to meet a guy that she knew through a sailing forum who had a boat in Turks and Caicos.

So immediately I realize that no guy is going to invite a woman down to his boat for two weeks not expecting to get laid. Then when she is down there she texts me and Facetimes daily telling me all about what she's doing, she misses me, etc. When she gets back we pick up where we left off and I don't care what happened down there but she makes a point of telling me that she didn't find him attractive, it was more of a friend vibe, etc. All signs point the other way of course and I am 99% sure she banged him while she was where.

Fast forward to last night, a month later and we are having a conversation and I basically ask her flat out if she did, and she confirmed that yes, she slept with him multiple times while she was there - even though she was daily messaging me and telling me how much she missed me. AWALT. Not a big deal, she is and will always be just a plate as a result.

What came up next and I thought I'd share is what her hamster came up with to justify it. She claimed that she "felt obligated" to sleep with him because he was letting her stay with him and feeding her, etc. Of course I laughed in her face when she said that and she got really embarrassed. And then proceeds to tell me how he would get jealous that she was talking to me every day. I thought to myself - why? - you're the one banging her currently.

So the thing is, I knew that she had done this. My gut told me so. But for some reason when she got back and seemed to be really into me my own internal nice guy BS dialogue started to tell me that maybe she wasn't like that. That she could spend two weeks on a boat with another guy and not have sex with him. Which is completely foolish. Gentleman, if your gut tells you something, then realize that it rarely steers you wrong and don't ignore it just because of some stupid inner dialogue.

Lessons learned:

She's not yours, it's just your turn.
AWALT Don't make a ho into a housewife.
