Feeling unwanted, down, and not sure why.

Me and my boyfriend love eachother so much! But idk lately things have been just.. at a downfall i guess. There is many reasons why i think so. Well, were both gamers. But he doesn't like playing with me. Lately since the beginning of the month he's been playing 24/7 with his friend on computer games. I dont want to be one of those girlfriends that are controlling and tell him to stop. But idk, im just not really getting any attention from him as much as i would like.. Everytime i txt him while he plays he forgets to txt me back. 2nd we've only had sex twice this month.. And both times im the one that asked for it. Idk if thats good or not. And when we do have sex, we pretty much go until he's turned on. We dont really so any foreplay and by the time im turned on he's finished.. How can i get his attention more? Im at a point to where im feeling down about us. Like i dont want to really txt him because its pointless. He's always playing games with his friend. We havent talked on the phone in ages. But he'll talk with his friend on Skype from 9pm-6am.. I need advice.. :'/
