<human>: I'll start this by saying that in my past relationships, I have always ended them at the wrong times. Either too prematurely over something stupid, or I stayed with the wrong person for too long.

So what's happening now is I've been dating my boyfriend for 6 months, and I am his first girlfriend. At the beginning, he was very sweet, we really enjoyed being around each other, and (not that I require this) he would pay for me all the time.

In the past couple of months, he has stopped trying. He said he can't pay for me except for special occasions because he can't afford it anymore, he has stopped telling me sweet things (he says that "after 4 months, I figure that those things are obvious"), and I've realized that he is really unaware of basic social rules.

It started when I was done exams and he said he'd take me out for dinner. Because I was studying for exams, we hadn't seen each other for about 2 weeks. First of all, he brought his best friend with him, and he was wearing basketball shorts. To dinner. And when I asked him about it, he said that he does not understand why it is unacceptable. Another incident was when his roommate's girlfriend let us stay in her house for a weekend, and when she asked us how we slept, he said "Bad, it was really uncomfortable." So I find myself having to explain to him basic things such as being polite and thankful to a host. The problem is that he generally doesn't agree with me and he is extremely stubborn.

I was living with him temporarily because he goes to school out of town, and some days he would come home and not even say hi to me. I told him it made me upset, and he said "Okay I didn't know. I'll say hi to you when I get home." But even though he agreed with this, I find it grueling to explain to him such basic things.

Can you give me a shortened version of the text?
<bot>: My boyfriend is socially unaware, stubborn, and his effort has significantly decreased in the past couple of months. Is there any hope for this relationship?
