What to do?

Think in love with this guy been seeing for 6 mths. He's been in drug recovery for 10 years, as a result is very self aware and honest. He's warned me that he shuts down emotionally as he gets closer to someone. We have had a very easy going but pionate time when together. Recently he appeared to act more keen and has told me he 'is really very fond of me' but he is saying more things to undermine/underplay the relationship, not into commitment etc. Noticed that although he has been the one instigating meetings, he only wants to see me once a week. He makes no plans and last time he told me he was planning to go on weekend break alone. Was hurt he didn't want to take me, and so decided to back off and see if he would make any effort to chase me more. Have heard nothing for nearly two weeks. I miss him very much, but daren't contact him. I am waiting for him to make more effort, to show he cares and wants to be in relationship with me. Am i doing the right thing?
