HALP!

So I'm a college student, and a few weeks ago my roommate and I threw a party in our apartment and one of our good friends from another college came and brought two of her friends. One of the friends she brought was a guy who I ended up hooking up with...twice, that night. The day after he friended me on Facebook and instantly started messaging me. He said he had a great time., and that he would love to hang out again sometime. We exchanged numbers and texted everyday for the next week. He would always text first, and by the end of the week we also started a snapstreak (which may be irrelevant, but not to the rest of the story). The next week he stopped texting every day and because I didn't want to come across as desperate, I didn't text him. We snap chatted every day still but only to keep up the streak, occasionally he would reach out on Snapchat to say hey or to comment on my story, but the texting had almost stopped. Two weeks after we hooked up initially, my friend and him came back over to our apartment for another party, but he didn't try anything and almost seemed to not pay attention to me, we had had a conversation before he came where he said we probably wouldn't be able to do anything because my friend(the one who brought him initially) wouldn't let us. He hasn't come back for a party since, we still Snapchat occasionally, and last weekend I went up to my friends college to stay in her dorm and he texted me at like 1 am asking if I was still up, figuring it was a booty call I didn't respond till the morning, and he didn't answer in the morning. He has also told my friend numerous times that he had a date the next weekend so he was clearly talking to other girls. I guess my question is does he sound interested at all? Is the fact that we share a friend who may not be completely happy with us together deterring him? Does he just want to hook up? Lastly, would it be weird if I texted him and just said hey how are you even though we haven't talked over text in over a week?
