How much alone time is typical or acceptable?

I’m really struggling with my captain not wanting to spend much time together.

We wake up, he leaves before me by about a half hour, but I get up, make his lunch and coffee and I get a hug on his way out the door.

We both get home at similar times in the evening but he spends a lot of time in his car... drinking, listening to podcasts, surfing the Internet, chatting with friends. I get home, make dinner, and he will come in to eat, then go back to his car.

I’ll do any other errands that need done, cleaning, laundry or whatnot, then read or watch something or craft a little until the kids go to bed. He comes in to tuck his kid in and then goes back outside to his car.

He usually, I’d say an honest 90% of the time, stays outside until I’m asleep.

I have expressed my need for more contact (we obviously have a pretty lacking sex life) and more time with him but it’s just not working. I have tried being my very best, wearing new clothes, getting new undies and make-up and jewelry, and I already do all the cooking, cleaning and household chores.

Is this excessive. I feel really lonely and abandoned despite my expressing my needs in a non-naggy way. I don’t know what else to do to express my frustration.
