Missing Ex boyfriend :/

I think I still have feelings for my ex. We split up about 2 months ago but I hadn't seen him because I was on holiday and now that I'm seeing him around I'm remembering all the times we had and I miss it and I miss him. We split due to constant arguing and lack of trust I had in him. I dont know why I miss him as he has recently caused many problem for me but I just can't help it. He was the first guy who treated me like i was a princess .

Anyone have any advice for me I need

it :(
