<human>: Can you condense the text into a few key points?

I am currently a stay at home dad with my 20 month old daughter while my girlfriend works at her business. 

It's driving me crazy being home alone all the time so I recently started trying to get out of the house. My mother in law takes my daughter once a week overnight so I recently started hanging out with some old friends once a week. My girlfriend seems to struggle with being left by herself (she is 8 months pregnant btw). She goes between being okay with me going (even encouraging it, even going so far as offering me "spending money" as she is currently financially supporting me), and then when it comes closer to me leaving, she usually acts a little crabby towards me. 

She claims we don't do anything together (in reality, we don't. 8 months pregnant girlfriend who works ALL THE TIME, toddler... how would we have time?) and is hurt when I chose to go out with my friends instead of take her out on a date.  In the end she usually agrees i need to get out, just feels like I am choosing my buddies over her.  Should I be more considerate of her feelings? Or should I continue to do my thing cause it helps me get through my week being a stay at home dad.
<bot>: pregnant girlfriend gets upset every week when I go out with my buddies, feels as though my night off should be spent with her.
