Sooo I've been having a gut feeling the last few months that the hubby is doing something he shouldn't be but didn't dig deep bc honestly I don't want to know or find out BUTTTTT tonight he came home and I saw welts on his shoulder and asked what it was and of course he doesn't know and I went to sit down and saw the SAME marks on the other shoulder so I snuck and took these picts. The first picture you can't really see that great but the 2nd pic you can and it looks the exact same on the other shoulder. What do you all think? I need some input bad!!
