So I've been dating my boyfriend for 7 months and we were absolutely amazing up until the 5 month mark...in the beginning he tried extra hard to please me, was super sweet all the time, went out of his way to be with me, etc. We moved in with each other in November and things were still great we even got into a dom/sub relationship which made us extremely close do to the trust and connection it brought...but now its like he quit trying, he's still a gentlemen but we fight a good bit (I know some is normal because for one we live together), the dom/sub stuff has basically stopped other than the rough sex (which happens less often too), idk things just seem different and bringing it up doesn't help it just starts arguments or he pouts saying he doesn't deserve me or its all his fault. Advice? I feel like in loosing him or is this just normal for relationships? Tips?
