he said he misses me

so I was talking to this guy for like 3 months. he recently got out of a relationship as did I. okay some background: we met at a bar one night he came up to me and started introducing himself. well we clicked instantly. im usually the shy type but I wasnt with him. we both agreed that we had a connection. well 3 months went by and he started to get distant and one night he messages me saying his ex wants to get back with him and he decided to go back with her. (yes it sucked) it hurt but I just went on. month later he tells me he misses me. I just dont know what to do. I was drunk when he messaged me that and I replied I missed him too. (cause I do) but I didnt want to tell him that. but i was drunk so it kind of got out. And now I don't know whether to message him and acknowledge that now. I never been the type to get in between a relationship I dont want to do that. but a part of me is like will I ever click like that with someone again? help.
