Need advice

Hey y’all!

So this guy and I have been hanging out pretty often here in there. We have a little bit of history because we’ve known each other since we were middle school age of the teenage years and lost touch and just kind of reconnected as adults not too long ago. At the time that we reconnected, I had a boyfriend and he wanted to hang out and do things that I could already do with my boyfriend. So I politely told him that right now wasn’t a good time. So when my boyfriend and I broke up I took some time to myself and then me and the guy started to talk again and we just started to hang out for the first time as adults last month. So he’s 22 and I’m 25. Things have been going pretty good..I have been enjoying the hangouts and everything, spending time with him and getting to Know him for who he is now . Yesterday he told me that he liked me since I was younger... I never really knew that he did because I don’t remember him verbally telling me so. But idk... I feel like he likes me still now, I mean he puts a lot of time and effort into seeing me. Should I tell him I like him too? Is he too young ? I just really don’t know what to do in the situation...when should I tell him hey, I like you too? We’ve gone out 5 times now . I guess I’m afraid that he may be to immature or he’ll just want to have sex and go his way, or he’ll just have me as a place holder. I have just been through a lot so it’s hard for me to trust guys . Please please don’t read this and not reply.
