<human>: Well as you know, I've broke up about 2 months ago and thought i was coping along nicely until i've started to talk with my ex again (long story short: the reason is I still love her and we broke up because i was too scared to face my own problems which relied on her too much up to the point where she actually gave up.). After chatting (she's coming back for summer holidays) over few days it started off as a simple "how you've been and exams" etc. then later she starts giving me these tiny flairs of hope towards me. As for me I was soo glad to see that she still cares about me. (during the 2 months i've learned a lot, what I was doing wrong and should man up a lot. I just have huge self confidence issues, always deny myself of what i'm capable of and doubted myself far too many times). 

The next day she seemed bit annoyed ( probably to travelling ) like that attitude "yeah, whatever". (and its bit hard to read emotions through chat :/) which was really odd. The latest thing was it snowed yesterday and was saying to her make sure you wear warm clothes getting out of the plane etc. and told her that i had to wear back to my winter clothes. She goes "well i'll just enjoy my stay here while u go do that" after these words i'm just lost. Clearly I don't know what to expect even what to do. So i just replied "hehe yep, Ok gotta go to work bye". 

Man I care for this girl soo much, it's just my stupid word choice and saying things without even considering the situations has dug me a big hole. Do you guys think we have a chance? What i'm asking is should I just keep on fighting to win her over until she finds another SO? or should I just abandon ship? 

thank you to whoever reads this post and hope you have an amazing day/night. Any advice is much appreciated :)

Can you condense the text into three sentences or less?
<bot>: started chatting with Ex, who I still love (broke up because of me), gave me flairs of hope then suddenly changes. Should I try to keep my relationship? or just let her go?
