I think I love my best friend

3 years ago a guy I worked with agreed to take my virginity. He’s 11 years older than me but we had the same job and were getting really close as friends. Now he is my best friend and I can’t imagine life without him. I was recently diagnosed with depression, I live an hour away from my family and my best friend and just haven’t been feeling like myself. The only thing that feels certain is that I think I want to be more than friends him. I went on a 5 day camping trip with him and his family and during that trip I could see myself spending the rest of my life with him. I wasn’t sure if it was just a vacation high or what. That was about 3 weeks ago and the feelings haven’t changed. My mom thinks I’m just moving towards what feels most like home because I don’t like my life right now. Him and I have never really had the conversation of us dating. His mom asks him why we don’t and he just tells her no I don’t know if they’ve had a real conversation about it or not. I don’t know if I should say anything for fear of it ruining what we have. I don’t want to lose him or make things uncomfortable, but I don’t want to miss out on a great thing either. Should I talk to him or wait a little longer to see if it’s actually what I want?
