When we were dating, my H (even though he later would always deny it) told me that he would NEVER put me before his friends or his family. That should have been a huge red flag for me, but I still married him. He NEVER did put me or our marriage before them either. We went to counseling where he declared that his dad was his best friend...dad who abandoned the family when H was 9 (now 40) and hasn't really been around for him since then. H had 2 foot surgeries last summer, and dad never even visited. We never got to create our own memories of any place we went together as he would fondly remember when WE went there or near there or anywhere. WE was his friends or his family, not us.
H once volunteered to take dad and his brother back to brother's home (2.5 hrs. from us) in case they had car problems but wouldn't come 45 mins. to meet me when I did have a car problem. He would drop everything if a friend needed a favor but brush me off when I asked for something. WE, again not us, always came first to him.
Being married doesn't necessarily move a relationship to first in line; our marriage certainly never came first. He's been gone 2 months now and doesn't have to worry about our marriage taking anything away from those more important to him.
