It's difficult. All I can say is that in the past, staying in relationships where everything was great apart from the sex, and where the guy wouldn't even try to meet me half-way or make my satisfaction a priority (just like I made his) didn't work in the long term. Resentment builds up and spills into other areas of communication, frustration leads you to look at other men, and this type of lack of eroticism and playfulness and thoughtfulness in your love life must manifest itself in other areas, too.
I don't think that lack of head is a good enough reason to break up if you can live without it, but I think it is a big issue when the partner isn't even mature enough to admit it (I mean, he could be like "honey, I want to make you happy but this is a hang up I have and can't get over. What can I do to you instead? Let's get those toys out!" but he doesn't). So you'll have to figure if it's worth giving up on these things and essentially being in charge of your own sexual fulfilment in future.
As for me, I think I could be with a man who doesn't like giving head - as long as he was honest about it, accepted it was a flaw in him and wanted and was willing to please me in other ways to make up for taking this act off the menu... I'd see it like the equivalent of being with a guy who has a small cock but would fuck me with a big dildo if I wanted that experience, or for a man being with a girl who has chronic tonsillitis and can't give a bj but would give sloppy handjobs with lots of lube. We can substitute sex acts, but only with good communication; it really is about feeling that our partners actually care and want to please us and that it makes them happy, too.
