I also want to add, that recently his brother and his brother’s girlfriend (of 7 years) broke up. After this happened I started to see a change in his attitude about OUR relationship. I have a strong feeling that this is part of the reason he seems so reluctant to fully commit… I just don’t know if I should leave the relationship until he feels that he is ready to commit, or if I should stick it out to see if he comes to some conclusion.
