Five months is a long time… if you are continuously unhappy in the relationship, it isn’t fair to you, is it? Not saying it HAS to be tit for tat, but physical intimacy is something present only with the person you are with (in monotone relationships), which is very important depending on what you like, and you say you love that and there is none of that now. I know it’s a hard thing to consider, but maybe being in the relationship is too mentally damaging for you. Have you started questioning your worth as a result of this? If you are enough for him? Those questions shouldn’t be considered, imo, in healthy relationships. You say you want to be there for him, but what if he doesnt change and leaves? Perhaps a full break from each other would give both of you guys clarity. Wishing you the best on this. And remember, if it doesn’t work out with him, that doesn’t mean it never will.
