What should I do?

My husband and I have been going through a difficult ass time. He feels like we got married too young and that he was sort of forced into marriage. He also wishes that he could have had that single life that he didn’t get to have because he has been with me since high school. Me and him had a massive fight and all this stuff came out and it’s been really rough on me. But now, he’s completely back to normal. And I just don’t trust it personally. You can’t feel those things and then everything go back to normal. We’ve already agreed on counseling, but haven’t been able to make an appointment yet. Is there anything else I can do to fix this? I’ve tried talking to him about it, but every time I do, he ignores the conversation. He won’t talk about it. Whether it’s me asking if we’re okay he just says we are and stops there. I asked him this morning how he can just go back to normal like he has and he didn’t answer at all, and yes he heard me. I just honestly don’t know where to go from here except counseling. I’m not up to swinging or threesomes, for him to get that extra “fun” that he’s wanting, so does anyone have any advice as to how to get through this problem?

EDIT: we’re a military couple, so separation isn’t the easiest thing. And he loves me, but he wants to “explore”, he just can’t decide if his love for me or his need to explore is more powerful ig
