I need advice... Lonely

My live in boyfriend is never home. I know he's not cheating, he stays in contact with with me through phone calls, text and snapchat, which I'm grateful!!
 But I still feel lonely that he never comes home to spend time with us, relax-with me or allow me to cook him dinner.
He always "has" to meet with a friend, fix something or help a family member.
I literally feel alone. The connection we had is completely lost and I'm starting to resent him.
I do not nag but I did bring it up once.
He says "It's just the way I'm wired" And he went on to say that he has never been someone to sit at home.
Which I understand, personality differences I suppose. I don't want to make him change but I'm feeling unfulfilled. 😢
I have tried going out with him, taking the kids with us... In hopes he would maybe say no to his other distractions for an evening or two in return. So he could eat dinner with us.
Especially because I had brought it up and suggested we make a balance. He was understanding but nothing has happened yet. 
I'm tired of fighting for his attention. 
I know he does not do it intentionally. He's kinda like a little puppy dog, just can't sit still. I don't know if I can keep up with him.
I only see him right before we fall asleep and then when we wake up.
BUT other than that, he's amazing.
Should I suck it up or move on?
I'm at a make it or break it moment.
