So how do u end a fling without actually addressing it? Lets try to figure this out, shall we?
1) Become busy! When he texts or calls, take your time answering. There's no need for immediate response, make it clear that ure not rushing. He will feel your lack of interest in your actions. Fill your schedule with things to do, atleast when he calls. That way everytime he wants to make plans, you won't be able to make it.
2) Improvise. If he flirts, acknowledge it, but dont flirt back. Become distracted by something, change the subject, or simply get out of the conversation.
3)Don't call him any romantic pet names. The main one is "baby" which is only used when u are romantically involved with someone. Don't even use babe because it can have the same affect. Try to stay clear of all pet names whatsoever, maybe even saying his name.
4) Don't be too sweet. You may be a nice person, but being nice to him can make him think that you still have feelings for him. Become indifferent to his plans or hobbies and don't be too interested in anything he says.
5) Don't linger in conversations. This makes it seem that you overlyenjoy his company, and makes him think that you're interested in seeing him! Remember, you're giving him the brush off! Brush him off!
6) If you hangout, hangout in groups! Being alone with him signals that you're interested in him. Make sure that you always have someone, or a group of someones, around when you're hanging out. This will give him the message that you see him as just a pal!
