maybe you could take some time to remind each other why you are together.
take him out, go on holiday, whatever. or something that you both did at the start of your relationship together.
i have found that there have been two main points in my 3 yrs with my partner than have made this neccessary for both of us.
1) about 18 months ago, he was assigned a massive case at work and had to almost literally live at the office to get through a mammoth amount of paper work. thus our time apart often outnumbered our time together. i started to feel frustrated and he tarted to feel distant. so once he finished the case, we took a trip to st lucias were some of his family are and introduced ourselves as a couple. that really helped us value oursevles as a unit as well as hard working individuals.
2)about three months ago, i had three of my trainers leave in the space of two weeks and i had to find replacements within a month, which had simiar consequences. so we spent a week off taking turns having a day ech to spoil each other, and the weekend to um...relax...
both times felt like the end of the world to us both, and both seem a bit silly now. but we had LOTS of fun making it right.
i dont know how long you guys have been together but these things just pop up. you could see it as an oportunity to wow him again, like you obviously did to begin with.
im sure that wont go unoticed, if he is a reasonable man.
but it starts with letting him know as you have
hope this helps
