Is it the antidepressants or is this ending?

I'm hoping someone on reddit can provide some support because I feel so lost. My husband has been on paxil for over a year to treat panic attacks. He has been growing increasingly distant. There is no intimacy in our lives and I feel like I have a roommate, not a husband. I've tried to have conversations with him how I'm feeling unloved, but he counters with, 'You're being overly emotional.' I don't know if he honestly doesn't care for me any more or if the meds have made him emotionally dead.

We've recently moved to a new state for him to attend grad school. I don't him to have to deal with panic attacks again, especially in school. But he isn't the same man. I'm heartbroken and not sure if we should reevaluate our marriage when grad school is over. I'm supporting him while he does this and I don't want to screw him over by throwing in the towel now. I don't want to do that ever, but I feel lower than dirt right now.

Any advice how to approach this? Is this an effect of the drugs? Or do I just need to face it that my partner doesn't love me any more?
