My ex and my new love

my ex moved away a few weeks ago and we had been going out for 8 months, things had gotten really serious between us but then she suddenly left and she said she might not come bk! I thought I would spend the rest of my life with her and I cant get her out of my head!

but there is this other girl that I really like but she has a boyfriend. we have been flirting a lot, she says she loves me and her boyfriend! whenever I ask her what we are going to do she always says she needs time to think about things and that things are a mess just now. this has been going on 4 about 4 weeks so far.
im really confused and have no idea what to do!

I need some advice, any will do!

You and this other girl only flirt and she says she "loves you, plus she "loves' her boyfriend? Does she know what love is? If she keeps using the same line , "I need time to think",and "things are a mess right now." Shes basically saying shes with her boyfriend right now, but if something happens between them, then it'll be your turn. Or shes just being nice, and doesnt want to come right out and tell you the real truth!
Move on and find someone that doesnt have a boyfriend!
