Venting. Give me your opinion.

So in the beginning of July I started talking to this guy. I just got out of a fwb relationship I wasn't looking to get into another one he knew that and eventually decided okay we could potentially date. I met up with him for the first time and we ended up having sex. And then sex again. I told him this felt very much like fwb but let's not label it anything. He agreed saying we are just having fun. Well 4 weeks later I decided I don't just want meaningless sex. I want a relationship. I told him that with the intention of thinking he'd not want to speak to me again but surprised me saying he didn't just want sex anyway although he'd miss it. What he said next was the part that slapped me in the face. He said if I was going to be here the full year I'd say we should date. He never told me he was moving! I felt like he should of brought that up from day one. Because I told him about me moving away down south to college this summer. He is 25 I'm 18. He could of said oh I'm moving back down south soon. He even told me us being fwb won't be affected because I'm not starting school for awhile and he isn't moving. But LIAR! He is moving either closer to his job or back down south in a couple months. I don't understand why he didn't tell me until I finally decided to end our fwb. Did he not think I'd have sex with him. I never looked at him romantically before didn't even think we'd stay friends afterwards and after he said we should date and that he wants to it made me start seeing him romantically and I want him. All of him. He's everything I'd ever want in a guy and he's leaving. We both have feelings for each other and he wants to continue talking but I feel like if I meet up with him now to hangout my feelings are just gonna grow and that can't happen. He says it sucks and wishes we had more time to at least have the opportunity to date and I'm like yeah it really f***king sucks! You could of warned me. I'm feeling mad and sad and hurt and I don't know what the next step should be. I don't want to even text him because I'm sad about our situation. We are trying the whole friend thing and we no longer text 24/7 and my feelings are like girl I need to be felt but I can't. I wish things were simple.
