Could my husband be married to someone else?

Raw moment here, please don’t tear me apart.

My husband travelled to his home country in July last year for his mother’s funeral and since he returned, I honestly don’t know who I am living with. My husband has not touched me since his return, he no longer sleeps on our bed and sleeps in the lounge instead, he is always working, the kids and I barely see him… the days that he is off work, he goes to work saying that he is doing over time. I don’t know why my spirit tells me that he may have remarried in his home country because how is it possible for a man not to have intercourse with his wife for almost a year? I have spoken to him countless times about this and he makes me seem like I am imagining things. Now the thing is that I am lonely. I need sex and you have no idea how many times cheating have come to my mind. I just want to be touched again. I bought sex toys and he was so mad at this and told me to get rid of them; as the stupid person that I am, I listened to him. I keep saying “divorce is not an option” and I want to keep my home for our kids, but is there really a home?
