I like a lesbian, but does she like me back?!

So I met this girl ( and im a girl)on a dating site online and she had posted in her info that she is actively seeking a relationship etc. so anyway we really hit it off we met in. Person a few days ago and I was so intrigued. I haven't felt this way in a really long time . I feel crazy because we hardly know each other but when her name pops up on a txt I get so happy and butterflies and the whole 9. She acts like she likes me too but we have only hugged , since we only met once . I really want to be with this girl she makes me feel so good and I just don't know. Any way we were talking yesterday and she said " I'm not much to fall hard over you know I'm messed up in the head" when we hung out she did talk about her ex alot but its been a year since they broke up. I have been hurt alot in the past myself and I feel if I'm willing she should be too but idk. And idk just how interested she is . What did she mean by she isn't much to fall hard over ? I think she's worth the world. But I'm scared to tell her I don't want to lose her . Or as much of her as I've got now I wan it to be more so badly it's making me sick . Also I'm leving the country for three weeks in 14 days. I don't want her to meet down one else or forget about me while I'm gone . I'm terribly smitten with her . Need some advice please!

it sounds like she likes u tell her u like her and ask her and if she feels the same, I think u should just go for it dont worry about it so much good luck ^-^
