If you phrase a few specific questions, I can respond via email system.
I think [after establishing the right time/setting], you should 'gently confront' him on this issue. Even though you've dated 'only' 3 months, that is long enough to get serious--as your admitted emotions [toward him] demonstrate.
If you let this go much longer [without ANY discussion], then it will likely turn into an "ingrained pattern" (as sociologists call it); and then it will be extremely difficult to change this pattern of behavior, let alone talk about it.
Without getting very emotional [I know--hard], you should bring this up and let him know that you notice; that you don't like it; that it's disrespectful; and that you'd like him to stop; but that you'll try to be understanding, and will help him through the process.
Hope this helps Cecilia,
