Am I wrong , vent about DH .

For the most part we have a great relationship together . Sorry if I sound like I'm whining or emotional ! I'm just really fed up with the lack of emotional support and family time I get from DH ! Maybe it's a new mom thing .. I'm home for the most part 12-14 hours a day by myself with LO and the days have started to run together and drag by ! It's so lonely . DH works hard to support us , and I'm thankful he has a good job ! It just seems like the last thing he ever thinks about is spending time with me and DS when he is off .. He's hasn't had to work weekends for a while now , but even though it's not manditory him and his boss are best friends so if there is any side work , touch up jobs ect .. They work . We'll he's been off on Saturdays for about two weeks now , and i expected him to want to spend time with his wife and son but we've either been at his moms or someone has been here . Keep in mind he never works Sundays and WE NEVER SPEND TIME AS A FAMILY on Sunday either. I was looking forward to a good weekend we'll yesterday he had to go cut his moms grass (she has a husband and an 18 year old son ) they are plenty capable of cutting the grass .. Instead he drives 45 minutes out if his way to go cut Two acers .. ? we'll today we went to lunch , I suggested we govswimmingvwhen we get home .. He said he wanted to relax so I went with it we'll we pull up in the yard and our neighbor was outside spreading dirt because something was wrong with his septic tank DH took it upon himself to grab a shovel and help ! He's very generous .. And kind hearted , but I often feel "pushed to the side " he came in and then went right back out to spread pine straw for our neighbor ! I've tried to approach DH about me just wanting to spend time together , it just seems that when i bring it up he argues with me in circles , he cast the blame on me and makes me sound selfish and disrespectful for wanting to spend time with my own husband ! He respects everyone else , but he lacks in respect when it comes to me .  I don't know what to do , I always end up in tears .. He has no problem helping others but if I ask him to change a diaper he makes me feel like I'm helpless and can't do anything !? It's became a struggle , idk how to handle this ! Why does he have so much respect for everyone BUT me . :/
