Thread: Should I tell him? Please Help.

It's a little complicated so i'll start from the beginning. Our relationship started off as friends because we were both going to major in psychology and we met in class and just started hanging out from there and we became great friends. We both wanted more from the relationship but we didn't want to say anything because once classes let out for the summer we were both headed different directions and it wouldn't work. But about two weeks before I left to go visit my mum he came by and I couldn't hold it in any longer and I told him how I felt and he told me he felt the same way. We went out four times and the day before I left he asked me if I would like to be in a relationship with him and I said yes.
But at the time I felt like if I didn't say yes then things would be awkward because we were in bed in the nude and it didn't seem the appropriate time to say "no".
So i went on my trip and was gone for almost a month through which we messaged back and forth and he confessed he loved me, and because I do love him ( just as a close best friend...if more I'm not sure) I told him I loved him too. I got back and we got together and went out and had great times and two days ago he came by with some flowers and a really sweet happy one month anniversary card he made. And I felt so guilty because i'd made nothing of the sort and quite frankly I wasn't aware that it had even really been a month and I just feel as if he's more personally and emotionally invested in this relationship than I am.
It's not that I don't want to be with him but I just feel as though maybe we're rushing into things too fast and I don't know how to tell him that without perhaps hurting his feelings or making it seem as if I'm not interested. He's also switching majors so it will be difficult for us to spend more time together because we're not taking the same classes and we wont be able to work on our assignments together, which is how we got close in the first place.
In the beginning I thought it was just going to be a simple hook up or a friends with benefits type situation, but now that it has sprouted into this whole relationship situation I'm completely lost as to what I should tell him. Should I go on with the relationship the way it is or tell him how I feel and risk ruining the friendship and relationship. It seems like it should be an obvious answer but since we have the same group of friends that makes things even more difficult.
Please help!
