so my (ex) boyfriend said we needed a break for a bit. he said he's sick of the ********. I tend to get a little insecure about stuff. he talks to other girls [like I talk to my guy friends] but for some reason, I always think the worst. we have been thru alot of stuff with the past year [with nonsense drama from other people, etc] & any other guy would've left. but he's still here. he still says he wants to be with me & he still loves me. we talked about marriage and moving in as well. so why do I feel so insecure?? and is there anyway I could try to stop it?
