You know, I really would like to hear my son’s voice again..

My son is 17. His girlfriend is 18. They have been dating for two years. In September, I found out he was no longer innocent and sexually active when I found his condoms + I went through his messages to his girlfriend and found d*ck pictures. I made him break up with her. I yelled at him, made him switch schools, took away his car, and made him quit his job because his girlfriend was a coworker. He became sad and he called his dad begging him to let me stay with him. I agreed because his dad said his house is closer to the new school I placed him in. My son packed all his things immediately. He didn’t say bye or even look at me. He would mutter things under his breath but I couldn’t make out what they were at all. As soon as he moved in with him, he deleted my number. He got back in touch with his girlfriend. It’s been like 3-4 months and he hasn’t spoken to me. I thought he would have been back by now and that things would be mended. His dad tells him that he should talk to me but he says no. I keeps asking my husband if he can take his phone to him but he always declines. His dad tells me that neither of us can force him to speak with me. So I am trying to back off. But I’m very sad and I don’t know what more I can do. I feel defeated. It hurts. A lot. I miss hearing his voice and his laugh so much. God I'm so fucking sad. I didn't wanna go into 2021 with him still fucking hating me.
