Ok one thing guys don't do is tell a girl they like that they
don't like their behaviour because it saves them an argument - they
tolerate it for a while.
You have to ask him and not get angry if he tells you that he does
not want to do it. If you get angry - you just drive him away,
that's all. Just talk to him as a girlfriend , not a mother.
If you want to be petty and demand trivial promises like this,
there is really no point in you having a relationship seriously.
You won't be helping yourself.
If sh*t is going to happen , it will happen because it is life . No
one's fault. You cannot keep worrying about the sky dropping on him
or if he runs away. You are insecure and sooner or later , that is
going to really affect a good relationship.
