Hello guys. I have this situation with girl that I like. This is complicated and long story, but I would try to make it as simple as possible. We were classmates. During the school years we had good relationship. I think there wasn't a day when I didn't made her laugh. We where like friends. But that kind of relationship wasn't as easy to be called just friends. It was always surrounded by mixed signals and excessive touchiness. She liked to sit on my lap occasionally during the breaks in school, play with my hands. When we were going to the next class we were holding hands and so on. These things were fun and become like natural to everybody around us. For time to time I would accompany her from school to her home (just the building, not inside), we would talk and so on. I was young and had no idea how complicated this relationship was. Of course I was ( probably am) a pussy and didn't asked her out, I was afraid of the embarrassment it could bring. To describe the story better. I was the fat kind in school, I wasn't like extreme fat, but I was big. In her case she is medium sized girl but the rest of her family are bigger sized. I watched a lot of american movies, and have heard stories how fat guys have skinny girlfriends, and I though this probably in USA only.(I'm from Baltics) Yeah I know, total bull crap. So my confidence was low and I wasn't sure I could land her. So I was still going for the same stuff just keeping it low, and not saying something I could regret and make fool of myself at that time. The relationship didn't changed, even when she got a boyfriend. The friendliness in school was the same, with kinky and touchy moments. So I thought that this is just how she is, even though this touchiness she did was just with me. It is worth mentioning that we were hanging out just basically in school, few times with mutual friends.( I know, I was pussy). So to the topic. She was in this almost few years of relationship with her boyfriend. What I've heard from people, is that they are in off and on state all the time. They are fighting and stuff. The reason that I know this only from others, because she doesn't talk to me about him at all. It looks like she is changing the topic when someone mentions him around me. So it was kind suspicious, but I didn't stick to it. One time, my buddy was helping her dad with computer, and she mentioned to him that she likes bigger, fluffy guys ( because her dad is like that). Well it gave me hope, but hope is useful when you have balls. The situation with boyfriend was complicated enough to begin this quest. So school is over, time for university. I went aboard and she stayed in my home town. During the holidays we meet with bunch of friends, and I get my dose of touchiness and stuff from her. During 2 years of studies I have heard stories that she went off and on with the same boyfriend for multiple times. But in the end they stay together. It is very broken relationship and everybody says that to her. One time we have talked about her relationship with that fella. (It was a party and we usually sit together if she comes alone). So she explained that he had a chance to be the one, but he fucked up multiple times, she knows that it is not healthy for her to be with him. But she is afraid to go and search for someone else or something, I don't remember exactly. So yeah. It looks like a window for me. I'm finishing my studies and in this summer I'm coming back home for good. But I'm coming with changes. During the years I have lost around 35kg and still working to achieve great shape. So yeah it is something. It boost me confidence and changed my mind set over the year of diet and fitness. This time when I come back, I don't want to fuck around and be the pussy I was before. I want to take what I want (or at least die while I'm trying
). I want to show her that I could be the one and I'm interested in her. I need an advice on how to achieve it, because it is not a simple situation in my case and I don't want to mess it up. Maybe some ideas how to really tell if she could be interested or not. (The last time we met with bunch of mutual friends, she stayed glued to me and was playful for all the time, my friend who showed me this forum, said to me afterwards. Dude why you didn't scored her yet? If you could be alone or something it would be so easy or something. But with her I can't tell if it is natural or it is messages that she gives all the time. Help? 
I hope I made it possible to understand. Thanks for your help!
