it dont work-my love goes to some else part 2

I tried to date someone like online dating it doesn't work for me like I did say vc and calls are poor connection and texting is sum thing else really I can't take it I don't feel anything and I will feel bad bec that person I was or am will or get hurt by me and like I only like one person but he´s my ex and broken up with him like last week and I can't get over him. it's how I go I like some then fuck I like some else but it's different for him I can only think of him and the only reason I did brake up with him is bec I get so much fucking pressure I just can take it any more like tf  I regret my decision really. and idk what I should do
