My significant other and myself do not live together. We both coordinated our schedules to take a week off from work so we could spend some extra time together. The week was a disaster. He wanted to have some alone time which I understand but he had made commitments to spend a couple of days with me all of which he backed out of or had an excuse. The only night we spent together was wednesday night when I had to share the time with his family because it was him and his brothers birthday that week and they had a celebration dinner. We spent some time alone after but had a huge fight that I dont even remember how it started. It had to do with him having some unresolved issues with his father and an ex from nearly 20 years ago whom he was deeply in love with but they had an abortion (his sister told him at the dinner his ex was pregnant and showed him a picture of her glowing with her husband and looking near full term.) Anyways... after this huge fight that we barely resolved or just let go without resolving, we didnt see eachother until Saturday where I reached out and went to his house to see if he was alright. He told me to come over saturday night and we would spend some time together. I go back over there saturday night, and I am not there even two hours and he was like, I am going to bed. Since I wasnt tired, I told him I was going home because I didnt want to lay in bed all night wide awake when I wasnt sleepy. Since this happened, I havent heard from him.

This is not the first time he has gone for days without talking to me, but I am always the one calling, and checking and trying to fix things and see if he is alright, and to tell you the truth, I am tired of doing it. Evidently he is upset about something, but I am not sure what since I tried to call on Sunday and he ignored my call and never called back. Should I try to reach out and leave a voice message or should I just back off and give him his space?
