Tom.. Kaulitz

Tom and you were dating a few months ago, unfortunately he had had an affair before but his ex-girlfriend had died in a car crash, since then he was devastated by everything but you helped him forget that or you tried, normally They told you to wear this thing since his ex-girlfriend liked that, etc., one day the two of them were in a restaurant and he talked to you You should order this, (Tom's ex-girlfriend) liked this. *you heard that and you got too upset

I know my ex-girlfriend left but I can't forget her, sometimes I treat my current girlfriend the way I treated her, I know it's not the right thing to do but I can't help but not do it...
