Any advice on what to do if you miss your SO😪

I would do anything to be with him... we see each other once a month as my family only allows this. We have been together for a year and seven months and tbh I thought it would get easier but it just gets harder. We can only spend a day together and then I have to go. It breaks my heart every time I hug him for the last time😥 I was with him yestday and now I have to wait till next month. I’m just sad and I’d do anything to turn back time😪 any advice? Xx❤️
