No sex life

So here’s my problem we’ve been together two years all was great now we have our own place together both work full time if anything I thought that would make us you know miss each other and so on. However my boyfriend doesn’t seem to want to have sex anymore he’s either too tired or just wants a cuddle or watch some TV... I’ve tried the hints which just leads to arguing I’ve even talked to him straight up and it goes in one ear and out the other, what do I do?!
