Hey guys this is my first time posting on here and would like some advice from you guys .. So i've been with my boyfriend for 2 years now and my Question is ladies how would you react if you guys have been together for this long and your significant other still keeps secrets from you?! Also attitude changes out of nowhere towards you for no apparent reason?! He watches porn alot and masturbates to it ALOT like its a real constant! I know a few times will be ok with me but the way he does it just kinda gets to me .. Am i wrong for getting upset and feeling alone and kinda disrespected?! Oh and not to mention the constant lying about small petty things all the time
