How long has he been talking to you like this, though? Do you think he would be willing to change the way he talks to you (I.e. not be nasty)? No man is perfect, true, but how you talk to someone else is almost always your choice... especially when responding to a text or email, where you have more time to think over your choice of words. What if he doesn’t want to change? Is the relationship acceptable to you as it stands?
