Most Helpful Girl
You can have something serious with your current girlfriend while the other ones are just some girls amongst other...even if you like them, it may change and be more fragile than your actual relationship.
If you want to grow, learn, and try being in a serious relationship I'll say you should stay with your current girl as you said you have feelings for her and it sounds like you guys are doing fine.
If you wanna flirt around and just want to play...go for the others. Like you said they are otherS! But I can tell you, I'm positive they don't like you that much...the odds that many girls are crying telling you right after you changed your relationship status on fb sounds so fake... I think they may be in for a spin and leave you alone just after you started showing them interest again.1THIS IS NOT RELEVANT ANYMORE
