My ex-boyfriend's cousin.

I dated this guy for 2 and a half years. We broke up in the middle of 2008. Last month I made the mistake of hanging out with his cousin whom I have known for as long as I have known my ex. We got belligerently drunk and started making out. The cousin told me it was a mistake and that it did not matter how we felt because it was wrong. However, he is still coming over at least once a week to hang out...among doing other things (wink). We don't talk about our feelings but we do show them quite a lot. He is a very affectionate guy and he makes my heart swell. Every time I text or call him, he always reciprocate ...but he is never the first to initiate a conversation. So... whenever he is not in town and hanging out at my condo, we are not communicating at all lest I put forth effort to stir up a conversation. I'm not the type to chase after a guy, especially one who is a cousin of my ex so I'm just leaving it as is. I cannot help but feel completely confused though. Why won't he try to talk to me when we are apart? If he feels like how he act whenever we're together then shouldn't be at least try to call or text? Or am I just another tool at his disposal?
