Starting to have feelings for close straight friend

Hey this is my first actual post (unless you count dog pictures, then it’s my third). Anyway I’m just looking for some advice on this situation.For a bit of context, I am 20 and this friend of mine is 21, we both got really close in our first year of college and we both took a break for unrelated reasons after freshman year. We plan on returning to school as roommates this summer. I have just recently noticed that I was starting to have romantic feelings for him. Now honesty is really important for me so I went ahead, after discussing with another friend of mine, and told him. He took it fine and was actually quite flattered, though said he doesn’t swing that way (as I had expected). I personally think that I am fine now, as I believe getting the solid no was what I needed. The problem is my mother believes that this will only lead to issues in our relationship. She seems rather adamant on this and claims that her greater experience with relationships lets her know this. I honestly just am not sure where to go now. Any advice on what to do here?
