I think it is time to have a very direct and honest talk about how this is affecting you, the relationship, and your sense of connection to him and that you are firm that this is a major, major issue for you and that it may very well mean the relationship cannot continue if this is not addressed.
Indeed the meds may be the initial reason for his plummeted sex drive, however it is on him to actually take the action to do something about that by going to his doctor (and no, the answer is not to “just stop taking them for a few days” on his own without doctor supervision!). This is where he, if he cares about you and this relationship, needs to take some responsibility for himself and what is happening and look at how it can be addressed in a healthy, safe and positive way (not just by stopping meds!).
I was in a relationship once where the sex just totally went away too, and much like you described, there was also no intimate kissing or other affection. Just maybe some quick pecks and hugs, but no truly intimate physical connection. Unfortunately in our case, he was not willing to really “discuss it” or see anyone. In our case there was no depression or medications. He was not having an affair or anything of that sort, but was resentful and used the sex (or lack of it) as a way to act out on that but he would not talk to me, or talk to a counselor, about it. In every other way he was stilll kind, considerate, and so on. It did not matter if I wore sexy lingerie, or told him how much I cared about him or appreciated him, or whatever else, and all it meant was I was constantly trying to find new ways of being rejected (well, it felt that way anyway at the time!). It was not about *me* not making enough effort as all I was doing was making efforts and I was becoming emotionally drained, sad, angry and frustrated. But the reason was…because I could NOT fix it on my own. He had to take responsibility too and want to fix it, and he just did not.
Things did not get better, and ultimately we had to part ways because obviously there were some major communication/resentment issues there to begin with given he was withdrawing sexually due to them, and the lack of sex just also killed so many of other intimacies that are important in my opinion and excaberated those issues. Slowly I became more resentful and hurt as well and my own emotional health and self esteem became pretty shaky as I felt constantly rejected. The distance grew greater until everything felt a bit “false”, like we were “pretending” to be partners but really weren’t (we owned a home together and everything so it felt like we were roommates in a great sense). I hoped things would get better but MY hope was not enough alone when he was not doing or willing to do anything to address it. I loved him too, but that was not enough to “fix” it.
Obviously the situations are different, but I tell you this story to emphasize how important it is you do address this and because while the “reasons” for the low drive are different, the effects it is having on you and the relationship, and his way of (not) addressing it is very similar. It is NOT going to get better by pretending it is not happening or just sweeping it to the side. I know for me, based on my personal experience, there is no way I could be happy with continuing forward in a sexless relationship, not for life. Even if for some reason I or my partner was unable to physical have intercourse, there would need to be other physical intimacies and ways to connect in that way.
The longer this goes on…and 7 months is already a long time…the harder it is going to be to reignite that physical intimacy even if he DOES get onto other meds. This is not something that can just “wait” even longer.
I really feel for you. Again, I know the experiences are different, but I think the emotional pain is very much the same. In my experience, things went on much longer than 7 months and by the end I was so emotionally “empty” and I would really hate to see you in that position. This MUST be addressed and he MUST do something actively to address it, it cannot all fall onto you, and if he does not you really need to consider whether you can live like this any longer, never mind forever. Physical connection and intimacy to me is JUST as important as him doing all the other sweet stuff, and there is NOTHING wrong in needing that intimacy too in a life partnership.
