<human>: My boyfriend and I have been together for six years now. I'm not really the jealous type. He's told me about his past relationships and it never really bothered me. I met the girl he dated before he met me really early in our relationship, and she was gorgeous and very cool to me. We're actively planning a threesome. It's on the calendar and everything.

But we were in his hometown last week and we ran into this other girl that he "dated." She's one of those girls who is trying too hard and comes off kind of desperate/sad/pathetic. She kind of made a play for him, which he obviously rejected. But when I asked him about it later, he said that she had a crush on him when they were in high school/college, and that she used to give him the occasional blowjob and whatnot. 

My immediate reaction was to feel like he kind of took advantage of her affection for him even though he didn't really feel romantically toward her. He was kind of surprised by my reaction. 

I flat out told him it was kind of a douche move and he was like she knew it wasn't serious and I was young/stupid and that was before I met you and you are the center of my universe and blah blah blah. In his defense, it was ten years ago but he still should have known better. 

I'm not angry at him or anything, but I'm wondering if I'm right to feel like that was kind of shitty on his part or whether I'm totally misguided.

Give me the gist of the text in a nutshell
<bot>: Boyfriend let a girl who had a crush on him give him BJs despite not having any feelings for her. Am I wrong to think it's a bit douchey?
