Any advice?

I found out about 2 mos ago that I am pregnant. I am now 11+3. Boyfriend and I have maybe had sex 2-3 times in the past two months. We both work full time jobs and on the weekends he has is daughter from 10-6. I have to be at work at 4am on the weekends so generally by the time she has Went home I am in the bed. I have been debating starting back to school and actually decided just a few days ago to start technical school in January. I fell down my back porch stairs 2 weeks ago and had a bad sprain where I had to wear a boot so I was out of work and in a lot of pain for a week. We have been looking at homes to buy since we found out I am pregnant and this pay check will really hurt my savings. My mind runs a thousand miles a second about the 20 million things I need to and generally when I get home as soon as my head hits the pillow I'm out like a light. That being said none of these things are a true excuse I don't guess but sex drive is just near nonexistent. If he puts a move on me I'm ready to go but his feelings are hurt that I never put a move on him. But I have so much to do before this baby gets here and as a result sex is the last thing on my mind. Anyways enough of my blabbering, today he told me he is sick of not feeling wanted and is leaving me. Honestly I am so crushed. I don't know how to fix this or if I should even try to because he said to only contact him if it concerns our child. Please ladies any advice at all would be appreciated. Just don't be too harsh my heart is already shattered as it is.
