Be there for him when he is sad, still show that you care for him, it doesnt always work, but that can get into a guy's heart
answer:
Yes....he can be....it's a possiablity
He probably got his feelings back for her
well did you ask her around someone? if you did then that's why she said that or she is probably shy flirt with her back then try asking her
If she still flirts with you, go and talk to her friends and see if she talks about you or if she told them she wants to get back together with you.
It sounds like hes a player you shouldn't get involed with it and it could cause you to be enemys with his girlfriend don't flirt back if this guy has a girlfriend his a pig
i say flirt back a little but not too much
she still flirts with because she is probably trying to make her boyfriend jealous... or get him back for something he did.
See if she flirts back with him, if so talk to her about it. If he is bothering her with it then make sure to step in and leave hints. If he still doesn't stop, tell him your her boyfriend and he needs to stop, because she asked him to. Good Luck, if she loves you, you should not have to worry! :)
Flirt back he will eventually come to it and see that he likes you to
Well you need to either talk to his girlfriend, or back away. Trying to get with a guy that has a girl already is bad unless he REALLY wants you.
Don't ask him if he likes you, but if you really like him let him know you do, but be subtle about it. Flirt with him more than usual. If he flirts back with you, than the odds are that he is in to you. Depnding on how he is, some guys are shy to ask out girls, so after you found that he flirts back wtih you and if you catch him looking at you whenever your around, then it is very acceptable to ask him out. My last girlfriend asked me out, and I thought that was really sexy. Hope I helped. Good Luck.
Yes he does, obvoiusly man this is basic stuff.
