Boyfriends...?

Mae
So. I need help, bad! My boyfriend and I have been dating for 5 months now but have been talking for almost a year.. I also deleted all social media for him. I've done him really wrong in the past, I'm not gonna lie but he's gotten "revenge" on me. By having a girl suck his private. Btw I've never done anything sexual with anyone else. But anyway, he works for that girls grandpa . His business is at the grandpas house and my boyfriend recently told me that she was there and she had tried talking to him but he didn't reply. My BF told me not to worry about it. Well, it's been 4 days and I haven't seen my BF at all! He ignores my calls (100 or more) and then when he does answer he says "what?" And then says that he's thinking. He doesn't reply to any of my texts and then when I get him on the phone he said "you're getting on my nerves" ... Everything was going so great! What is happening? Any advice on what I should do?
