Search Results: when girls suddenly lose interest

I use to be a pretty chubby girl. Not morbidly obese, but definitely not at my ideal weight. I finally got my shit together and lost it all.

Anyways, about a year ago I took an interest in this guy and I REALLY liked him. I was totally (and still kinda am) completely head over heels for him, but he flat out rejected me. Now that I've lost a considerable amount of weight, he's suddenly became very flirtatious with me and even asked me out on a date. I don't know whether to be happy and go forward with pursuing the relationship or pissed because it took losing weight for him to realize that I was worth dating?

Ok, so i'm in highschool, 15, female. I will give some back ground. I will use fake names. Tim is my ex and Ben is my current interest. Tim and I are kinda not friends but not unfriends, we were together a year ago. Tim and I are friends of a casual nature. Ben and Tim are in most of my classes, one of them being sport. I was walking around with Ben setting up some sport stuff. the joke was something to do with drugs, and I replied saying I know who your dealer was, it's Tim. (This is a joke no ones on drugs) But Tim always jokes about supplying drugs. After the joke, Ben was like "So you and Tim, went out?" and I was like yeah "About this time last year." Ben was like "how long?" and I said "Like a month a bit." (I realised I wasn't ready.) Then he said "You two were the perfect couple." The convo kinda ended there. But later Ben came up to me when i was umpiring a game and we talked but then suddenly he was like "Why don't you go watch Tim?" and some other stuff and I replied "It was a year ago, you dick." He also teases me about other stuff. He asks weird but not really personal questions like "whats you favourite orange juice?' and stuff like that. As soon as I feel like we are getting somewhere he drops the convo/ loses interest. Is this a 'as long as I keep you interested, you won't go anywhere, have a flirt around kinda thing?' Someone else picked up on it one time. Another guy noticed the flirting and made a comment about us two together but neither of us really answered. He doesn't talk to me online that much. He's not much of an online guy though. I feel something there but he also has a lot of girls who are friends and I'm not crazy about him but he makes me smile. I don't want a serious relationship. But I would like to know if I'm wasting my time and should stop the flirting (that is accruing both ways) or if there is something there. I am being to cautious, but I don't want to ruin the friendship we have so far. So, what do you think?
