The best way is to ask him. some people hide their feelings too well.
Call him and ask him to have sex with you
You should ask her why she's upset.
Ask him ! And if he deosn't tell you - he's acting immature and childish. ASK HIM
you should ask him if he is mad and if his tone of voice change then he mad but if it dont change then he is not mad
Because your relationship lacks trust.
The best thing to do if you are mad at your boyfriend, is to remember all the good things about them. Remember the things that make you laugh, and smile. What they do that makes you happy. Step back and assess the situation, and make sure that you really are as mad as you think you are. You wouldn't want to do anything that would mess things up between you. If its a big problem, try and talk about it. Try not to yell, and ask questions, to make sure you aren't wrong about the entire situation.
You answer the phone and talk out the problems. You tell him why you are mad and try to work things out
You shouldn't be mad just find out why. The question is ARE you mad? If you are, you have to ask yourself why. Are you jealous or worried that your boyfriend may be unfaithful? Are you worried your boyfriend still has a romantic interest? Talk to your boyfriend and maybe the two of you can come to an understanding. If he talks to his ex as only a friend, then there may not be an issue.
Ask him why. Or talk to him about it. He might only be struggling through something else and is taking it out on you. Intentionally or unintentionally.
It would be hard to say why your boyfriend is always gets mad at you without knowing the situation. It could be because he is jealous, you are spending too much time together, or he may have lost interest in your relationship.
So your boyfriend got mad when you told him you wanted him to share you? As in share you with another person? You're boyfriend probably doesn't want the competition or sees relationships as being between two people, not three. Unless I'm interpreting you wrong, I'd say he just wants to keep the relationship between you and him, and I agree.
