Should we keep dating?

Anonymous
So I met this guy about a month ago, and as soon as we met on a party he asked me out. He is 24 and I am 27, so at first I said no because I felt weird about the age difference. We kept talking and sering each other because we have the same friend group, and eventually he asked me out again. He is a really nice guy so I said yes to give it a try. I enjoy spending time with him but I dont know if its ok to keep dating him. We have been dating for almost a month and I dont feel excited when we meet and hang out, it fells like “meh”. There are a couple of things I dont like about him like he is very unhealthy, doesn't eat fruits, vegetables, he always orders food and has terrible eating habits, he drinks like 4 days of the week with his friends (he is still in college), he doesn't work out a lot. I enjoy going out and drinking and smoking too, but I do it maybe once a week. Apart from that he is actually a really nice guy and he actually works (he has his own business and its going very well). He is very caring and I have fun with him, i just dont feel excited when we g out or anything. I feel a little selfish going out with him because he always tells me he really likes me, and i still have my doubts. Should I continue dating him and see where it goes? Or is it better to just stop dating him at all? I kind of want to see if I develop feelings fir him but I dont want to be selfish and hurt him since it seems he is more into me than i am into him.
