How should I treat these people?

I've started to feel quite upset and more recently angry because it feels as though I am always the one to make the first move with friends but never get it returned. For example it is always me inviting others round to my house for a game of cards or to watch the football or it's always me sending a text to invite someone out for a drink or to go play a game of pool but I just don't seem to ever get it back. I try not to take it personally but I've got to the point where I feel really resentful of them becuase I just don't understand why they seem to be so selfish. I've even mentioned it in a jokey light-hearted way and then at times in a more serious manner but it just doesn't seem to make any difference. Lately I've started wondering if it is just me or do I just have a group of friends who aren't actually as much of a friend to me as I'd like to think they are. I just don't know and I wonder if anyone else has ever felt like this?
