I love my man, I really do. we've been together over five years but something that aggravates me is that he has trust issues stemming from his volatile marriage to his ex wife, ie he can make comments about me cheating or being dishonest with him when I'm not. he saw some random friend request on my fb from a dude I don't know which I promptly declined and assumed that I must know him etc. he then made dumb comments about hoping I'm not a backstabber which at this point in the game 8 months preggo with his kid I'm like really bro? so I unleashed on him and told him he needs to get over his issues and fast because I am not to blame for them and do not want our son raised by a paranoid non trusting father. everyone gets insecure but cmon REALLY?!?! GIMME A BREAK.
