If he is with someone else then he is not thinking of you and if he does start to think of you that is because he is unhappy in his new relationship.
Tell her! ignoring her would make her want you more.. or get someone else to tell her
Not really, but you shouldn't make anyone feel left out.
Constanly talk to them and poke them xD
Ask them "Are you mad at me?"
I would think so. It depends on his attitude towards you.(Romantic,or harassing?) If he starts to bother you, I would confront him about it. If that does not go well, get PROFESSIONAL HELP. I wish you best of luck.
No wonder the poor guy is ignoring you. It appears that you can't make up your mind and you've hurt him once and I think he get's the message. You can't play around with people's feelings. If it was love you would know it! When you love someone you don't play games .. you either love them and can't get enough of them, or, you're just friends. There is no middle ground here. If you have to ask if you may love him then you don't. Marcy
by ignoring you
If someone is bothering you or disturbing you, you could either tell them in a nice way to stop bothering you. Or even try ignoring them. If they persist to bother you, you could seek help from an elder person you trust.
eat alot
You have to try harder to make him or her to communicate with you.
Breaking up with someone you always see is never easy. Honesty is the best form of communication if you want to break up with someone and it not be weird.
If someone's already taken don't flirt with them, don't gain feelings for them, don't make them gain feelings for you, don't make them confused about who they want, & don't be a home wrecker. Cheating, if you want to cheat then face the consequences. Just stay single if you want to flirt like crazy; don't hurt someone because of your recklessness.
