Advice please ladies!

Ok i already posted a few times on here asking for advice on this matter but i think this is pretty much the last straw. To summarize: i had a fling with a guy in the summer, we were great, we had sex the day before he left for college, he said he saw a future with me and still wanted to continue talking and see how we r with the distance. A month later, he is coming home this weekend and we are planning to see each other. However, he has been treating me like shit. He is very short with me. Only texts me for like ten minutes and then abruptly says goodnight, he is a bad texter but he used to be a lot more flirty. It is just stressing me out and i am miserable. Tonight, he texted me and i was excited to share the news that i am teaching myself a new language (Korean😊) and he answered so rudely and uninterested and it's like he's expecting me to fuck him this weekend? absolutely not. so basically should i send this text? he is not my boyfriend. but we like each other. i tried to end it like two days ago, and he said he wants to continue. but i just cant do this anymore. my gut is saying he isn't interested and is just keeping me around so he has someone to have sex with while he is home. so should i send it next time he texts me or wait until he comes home and just not sleep/kiss/anything physical with him and see how he reacts?
