Feeling like a lost cause

I am currently 8 weeks pregnant and have a 2 year old and a 14 year old . Been with my boyfriend who is the father of the youngest and baby to be for 3 years . He has been saying how he doesn’t feel loved or wanted . Says that the routine we have of family life is boring and I don’t do enough to make him feel wanted and loved . He says i have gotten comfortable and so into my routine that he feels like he is just a body here . It sucks this is the situation and I want to try my best to better it despite being tired from working and parenting . He has been a great father and makes sure I’m fed and everything is okay . How do i improve my energy and optimism to do what he wants me to do and make him feel better ! All advice is appreciated !
