Is it normal to feel this way about my ex?

I've liked this boy for years and years and we never really thought about getting together, and then he went out with a girl for 13 months and a few weeks later after they split me and him got together, I really enjoyed his company and he enjoyed mine. At the start of our relationship he asked could we not take it too serious an just see how it goes, which was fine with me because I was that into him I wasn't really bothered just knowing we were together was enough for me. After 2 months of being together I was totally in love with him and I kept telling him and he said it back but I didn't want him to feel as if he had to say just because i was, so I explained to him that I know he obviously doesn't feel the same but I love him to pieces and he said to me he wasn't ready to love someone so much as yet because of his long relationship before, which was fine with me as I kind of knew, he told me even though he doesn't love me, he loves spending time with me and the laughs we have together and everything's fine at the mo, and then 2 days later he finished with me for no apparent reason, I still don't know to this day but we finished about 6 weeks ago now and I think about him everyday I just want to spend time with him like I used to and I want him to know how I feel but I don't think I should tell him because I'm afraid of his reaction. Is this Normal? And what shall I do next? No horrible comments please just some advice, thanks
