Be open and kind. Engage with his feelings and opinions while being loyal to your own. Be considerate, and don't make him do things that irritate him. Make him envious or worried out only to get him to hang out with you. If he doesn't then it's time to find someone who will. Don't force him to spend time with you if he doesn't want to. Maybe he has other plans and wants you to be able to spend time together without arguing all the time. If this is the case then let him help you work through any issues you have before deciding what role you should play in each other's lives. Try not to take his lack of interest personally. Some people just don't like others outside of their group of friends, and trying to change this would be a huge task for most people. Remember that relationships are about compromise, so if he doesn't want to spend every single day with you then understand this and move on. Look for guys who want to be around you too and you'll soon find one!
