fwb basically told me he loved me and I'm over the moon but also so so so nervous to see if he really means it all

So I was completely ready to end my friends with benefits situation. We've been sleeping together for about 6 months. He can be very sweet and doting and kind, but the next minute he's insanely jealous because I'm going out with someone else (Because we're just fwb, I'm allowed to date. he's allowed to date. That's what the agreement was, but then he started giving me hickeys everytime he knew I had a date and he kept covering my cleavage in pictures to other guys as well as taking pictures on my phone of us together so that if anyone looked at my phone, it looked like we were dating). So I thought he had caught feelings because of the jealousy he was showing. He kept telling me "No." saying that he didn't have them. I was the one who suggested we be FWB in the first place. So I just had kinda written it off. Anyways, I was about to end it because of the jealousy and the fact that he kept denying that he had feelings. I was sick of the back and forth and feeling like I was never getting the truth from him. Well then the day I was thinking about it, I had two people tell me I should just end it because all I'm doing is hurting both of us and they said that I was going to get hurt when it was time to end it. So I was going to end it now before we got anymore attached to each other. So I went over to his house to tell him. I started out the conversation kinda casually just mentioning what they had said to me that day. Then he blurted out "Who says you're the only one who is going to be hurt when this ends...?" I paused and looked down at my hands. He leaned forward and said "I care so much about you. I want to see you happy. If ending this will make you happy then do it, but if you see a future with me at all....wait it out. I want to get my shit together before I properly commit to you. I want to have a life that I can bring you into. My life is kind of hectic right now and I don't want to dump that stress on you. Which is why I agreed to the friends with benefits in the first place. I wanted to keep you close because I care so much about you, but I didn't want to scare you off and I didn't want to bring you into my crazy just yet. I want to fix myself before we begin this. Please...wait this out, just a few more months. If I haven't figured it out and you still want to move on, then please do. I want to see you happy, but I also really want to be with you..." And like that whole conversation cleared up so much for me and made me feel so much more relaxed about the direction we're heading in and I just hope that he really meant it all...
