<human>: My boyfriend and I have been dating for 3.5 months. We are in our last semester at uni and after graduation will most likely go our separate ways. It will be hard and we will keep in touch but we think it is the best thing to do because we will be in different countries and we don't think it is plausible to do a LDR (for an indefinite period of time). We spend every night and most days together. It is worth mentioning that we were best friends before we started dating (and the way we started dating is that I had a LDR with a guy back home for 4 years and ended up leaving him for my current bf). We were both pretty damaged in the beginning of the relationship and refused to admit we had real feelings for each other. 

Now we hang out all the time, are super close, he helps me with work, I do the same, we hang out with his and my friends a lot, we have a lot of great sex, and we tell each other we like each other all the time. We have about a month and a half left together and I've started to fall in love with him. I really want to tell him because at this point I do not see why not, even though it'll have to end eventually. The thing is, I don't know if he feels the same way and whether or not it would ruin things if I did. We are going away for a week with his friends on holiday in a few weeks and we'll still see each other after that before graduation. We are even talking about going away on our own for a few days at some point.

I just don't want to mess things up but I really do have strong feelings and I need advice on how to voice them. Is there any way I can tell if he loves me before I embarrass myself unnecessarily or ruin things?

Can you summarize the given text in a few sentences?
