Kinda Just thinking outloud

So Late last year I ended a physical(3year) relationship with my ex. only because I moved away and the distance was kinda killing things. shortly after the break up I reconnected with a old friend who had a crush on me in high school , me being sad and unsure about what I should do I start to vent to him and I felt better when we hung out, so of course things got emotional and we jumped into a relationship. a few months in I realized that I was still in love with my ex . it's been 7-8 months with the guy from high school but me and my ex keep in contact almost everyday . I know it's wrong I would feel really bad if he found out and it's a little too late to say "hey I'm still in love with my ex let's not be together" I want my ex in my life but I dont want to hurt my boyfriend
