Relationship anxiety

So I got together with my neighbour who I knew for a year for about 6weeks before he left to Ireland where he was originally from, he made it official that we were together and we've stayed in touch everyday, I'm going to u.k in 2days, he wants to set up this future with us and is telling me he wants to love me forever and has never loved anyone like he has for me, super sweet guy, gorgeous, but I'm freaking out, I don't think I'm ready for another relationship, I haven't been single in 5years, straight after the last one ended I'm with this new guy but I have so many issues and stuff going on with me right now and I feel like now isn't the time for a relationship although I have feelings for him and I don't want him with anyone else, I feel like I've broken my own heart and his. But the thought of this relationship is making me feel sick with panic and I just don't know how to handle this situation, I told him I have problems etc but I've also told him I feel the same as he does, and I have, I guess I just hoped it would work itself out but now I'm not feeling good about it. My ocd has been terrible because its a new relationship I have to try and avoid issues by ocd ing everything and its exhausting and I'm not going to get better like this. It be easier on my own with the pressure and expectations of a relationship, its time for me to be me and focus on me but I feel terrible I'm going to let him down, I don't want anyone else to have him, he is wonderful, what should I do!!!!

So should i break up with him completely but stay in touch? This whole love thing freaks me out, there's a danger in loving somebody too much and I feel like were getting closer and its freaking me out because I know I'm not ready and I don't want to break my heart and his even more than it will. I opened up to him last night about some of my anxiety and the symptoms I get I thought that would make things better but I still feel like I'm not ready 😔
