Search Results: being honest about past relationships

Alright so as I said I broke up with my ex a few months now (March 2014). We go to the same school, the same class to be exact. We talk everyday very friendly, have a laugh and generally are very cool with each other. I'm in a relationship for a week now with a girl that I really like and care about. She also has been in one for a week (talk about timing huh). As I said I'm more than happy with this girl I'm seeing and I DO NOT want to break up with her anytime soon. I just have this weird feeling these past few days. She (my ex) was my first relationship and I think I always remember her for that but especially since Me and her have been dating other people I have been thinking a lot about her. I'm not sure if I like her but I definitely have still feelings for her. (This will sound very selfish and arrogant but this is the only place I can say what I really think & want). Here it goes: I want to be with my current girlfriend for a long time because I really like her but slowly I want to start winning back my ex without of course doing anything with her as Im with the other girl. Is there a way that I can flirt with her and make her want me again without #1 making obvious that I want her to like me, #2 being obvious for others to see that i want her to like me, #3 ruining my relationship with the other girl? Also, i don't know personally the guy she is dating so I don't care about him breaking up with my ex etc (i know its a bit mean, im just honest). So to sum up: I want my ex to slowly start to like me again without ruining my relationship with my current gf. Is that even possible? If it is, i would appreciate it a ton if anyone could help me with this. Thank you for making it this far into my question and if I have spelling/grammar mistakes sorry im not from a English speaking country. I can use every piece of help I can get so Im open to anybody's opinion :) thanks again
