So I've been dating this guy for 9 months now and in a short time we've been through a lot, in the fall we experienced a miscarriage which was really challenging for the both of us but it seemed to have brought us closer, and we've had trouble with both of our exes appearing out of nowhere and stirring up some conflict, but yet we still remained steady and solid and worked through it. however, he was acting weird the other day so I checked his phone and found that he was sending nude pictures and videos of him jacking off and planning nude Skype dates with a girl from new Jersey that he met before him and I started dating, I confronted him about it and his excuse was that he didnt feel good enough for me and wanted assurance from someone else. what do you guys think? any advice? :/
