Dreaming with a certain person constantly!!! What does it mean?

I'm happily married to my husband and we have a 10month old daughter who is our everything. I'm happy with my relationship of 7 years but for some reason I keep dreaming with an old high school BF? I honestly didn't consider him my BF at that time but he would tell everyone we were going out and all that. We would only kiss here and there because he would steal the kisses lol we were both student aides for the same office and period. He would find me when we were in the middle of doing errands for the counsellors and would grab me and kiss me. He would also walk me to classes. He asked me to homecoming and all that. I honestly felt like we were both in love but I never considered him my BF because I felt that by allowing him in my life he would ask for too much (sex) I wasn't ready for that and plus my parents didn't allow me date at the time. I had so much respect for my father. So I think this guy got tired of trying and all and started dating another girl. I got jealous and heartbroken!! 

After all that he switched schools and I didn't see him for a year. He comes back our senior year acts like there's still something there but at that time I didn't focus on that. I had my eyes on this other guy who happens to be my husband now 😍. 

But anyways after all these years we've bumped into each other here and there and have mutual friends. The times I've seen him he gives me that look again like he did before. 

I have him on FB as well since he added me right after high school. 

So yea I still know what's up with him nowadays lol I post pics of my husband and I and all that and it seems like he NEVER likes them or anything. I know this because I can see who's online. 

I just want to share that after all this I keep dreaming of him non stop. I don't think of him during the day but at night is when I dream of him. I wake up with all these feelings that I go through in my dream. I dream of us reconnecting in a beautiful way and loving each other 😫 I feel bad because I love my husband and I can't see myself cheating on him or breaking his heart. I can't do that because I love him. What I don't understand is why am I dreaming of him!!!!!

I don't understand!!! I need advice in what to do.
