Should I walk away

So me and my husband got in a huge fight last Thursday and he left we haven't really spoke he blocked me on his phone and I haven't really even tried to reach out. Today was our daughter 7th birthday and we were supposed to go to dinner as a family and he completely blew us off I don't know what to do I don't know what to feel my heart's completely broken but I can't seem to cry I feel like he has chosen his friends and being single over his family he doesn't want to hear my pain that he's caused anytime I kind of feel like he doesn't even care should I walk away or should I keep pursuing the relationship we've been together a little over 10 years please help
