Breakup

So I’m not one to post about my private life but I could really use some advice. My boyfriend and I broke up and he has some like clingy problems but not the cute kind the kind that feels like it’s suffocating you. Anyway so I told him I couldn’t do this right now and needed some time to myself but he he said that I was the only thing that made him happy but this guy was also my brothers best friend and we live in a farm and he helps a lot on our farm and he goes to church with us every Sunday and we see him. A lot. I would just appreciate some advice as to how to deal with always seeing him I guess.
