I know how difficult it can be, when you want somebody to lean on, but there's nobody there to care for you or comfort you in times of need. I've always been single so I guess I have developed ways of being more emotionally self sufficient because I have to be, because it is only ME that essentially has to deal with my emotions, it isn't somebody else's job. That said, you are still entitled to support in times of need, but that can also come from your family and friendship network - sometimes the best support is spending time doing positive activities with friends - that way they will often not feel burdened by your angst. While it's fine to have somebody to lean on once in a while, you have to act really as if you don't have a boyfriend - your relationship can grow and become healthier if you have your own life and own strength, because then you can give to your boyfriend. He might seem unemotional and have less emotional swings than you do, but it is likely that he equally has times when he feels crap, but deals with them differently, especially as guys are socialised that being openly emotional is negative.
