Does he not want a relationship?

Time to get a new Boyfriend! Obviously he doesn't respect you and he gets irritated with little things. Just imagine if it was something more than reading directions. He is with you for some other reason than "Love".

I just think he may have a bad temper. If you're really getting bugged by it, if it hurts you a lot, tell him about it. I'm sure if he cares for you a lot, he'll mend his ways. Take care!

No respect = no love. It is impossible to have a good relationship without mutual respect and consideration. If he's calling you stupid, then he definitely doesn't deserve you, and it's only going to get worse the more comfortable he gets with you.

I'm so sorry you're in this situation, but it sounds like you really need to get out. Talk to him first though - best case scenario is this is just the way he and his friends tease each other and he's carried that over. Whatever the case, he needs to know it's hurting you and stop that shit cold turkey. I've always believed that everyone deserves one chance to mend their ways, but if they don't change after promising to the first time, they're not going to change the hundredth either. Take care of yourself.

Definitely time to find a new boyfriend, or at least confront him about this behavior. If he's calling you stupid, then he's obviously not caring how you feel. This could lead to a whole world of bad, if it gets worse. There's no sense in being in a relationship where he criticizes you. A boyfriend should be supportive, no matter what.
