Lingering feeling to end things with my husband

We just had a baby three months ago! But it seems like he become a different person. We both are stay home parents. He works part time from home and it doesn’t even take much of his time. Flexible schedule if you will. I just finished my degree so until the baby gets old I’m holding off work. I came to the states and met him and stayed here to be with him and we had our baby and got married.

Now that we have the baby, i feel like I have two babies. He won’t sleep till late like 3-4 am playing on his computer or talking to his friends and then won’t wake up until 2-3 pm. In the beginning i would be bothered and i have tried kindly telling him encouraging him asking him and then I started to get angry at him because he would oh yes tomorrow I will wake up early and wouldn’t. Sometimes he will wake up for a brief moment and say are you mad I’m sorry and then 10 mins later go back to sleep. Now I don’t event have the energy to be mad because of my newborn. He also wouldn’t sleep in the same bed with me because he says I will wake you up if I come in or I move too much or i don’t have space when you co sleep with the baby or I’m making too much noise. Always excuses as if it’s all for my sake. At night I try to stay awake for him so we can spend a little time together but then he will be on his iPad playing games. Then recently he told me that he is not feeling sexual drive anymore so we haven’t been intimate for over 6 months.

I believe that he is not cheating on me but even if I have trust in him im a being delusional? I’m a wrong to wanting to give up on us ? Is it me being emotional after giving birth ?
