Is it ok to cry in front of your girlfriend ?

Usually I never let my girlfriend see me cry but I can't take it anymore it's because of these stupid internet trolls who just don't understand what's going on in my life. By the way my girlfriend is gonna have my phone for awhile I don't want it or even look at it I'm just too upset and depressed I may even delete my Yahoo Account and Similar Worlds and Reddit for awhile until things calm down for me if I can figure out how. I'm just trying to help her I keep getting judged and trolled for it I feel like I'm evil for doing this I wish I hadn't done this is there anything wrong with being apart of a child's life even if it's not yours am I really evil for this. This is gonna be my last question for awhile. Is it ok to cry in front of her ?
