Lack of sexual activity

Anyone else seem to have a lack of sexual activity after their first pregnancy? I had my daughter almost 2 and a half years ago and my sex drive has gone way downhill. Like I have little to no interest. I feel like I only do it just to please my husband because he gets mad when I don’t. Then doesn’t come to bed for another 5+ hours. He has started talking to other girls at times to get what he wants since he can’t get it from me at those times. What can I do to bring my sex drive back up?
