I think we maybe drifting apart?

Hi my husband and i are newly weds we have been together for 6 years but only married Feb of this year.
We have 3 kids also and we are both still in our early 20s.

For the past 3 weeks I feel like we both have drifted apart from each other emotionally.
Sometimes he'll tell me he loves me but it's not very often, sex life has been terrible although he always makes sure that I am pleased before he is.

He also has been wanting to do things on his own. He never really spent much time with me and the kids anyways but it just seems that when it comes to anything besides us he will do it no sweat, but this week everything has been getting a lot worse we haven't really spent much time together, he will either want to go to his gardens or watch TV when I go to sit near him he will go and jump on his computer.
I just feel like we are drifting apart, I just feel like he wants to be away from us.

What do I do or say?
At the moment I haven't said anything to him and I'm hurting a lot but quietly.
