Me and My Partner (Husbear)?

Hello everyone! My name is Edward and I have been in a relationship with my husbear, Larry, for 13 years. It's bittersweet, mostly sweet but the bitter parts have caused a great deal of pain between us that have gradually gotten better over time. I met him when I was 24 and he was 36 at a coffeehouse we both frequented. I would love to tell the story of how we met one day. But he was into guys like me (chasers) and I always had repressed feelings for guys like him (bears). Before I met Larry, I only dated and had relationships with women. He is the first guy, and the only guy, I've ever been with. Over time we both revealed our feelings for each other and I moved into his apartment after he begged me for weeks. He was a computer programmer now professor at a local community college in computer science. And I am a writer for a newspaper. He is Jewish so I studied for a year with a Rabbi and converted into the Conservative branch. We had a Reform commitment ceremony as they were the only branch officiating at the time then. We had a boy from a surrogate mother who was a friend of Larry's. Larry wanted to raised him Jewish, so we had him circumcised on the 8th day and he attends a Hebrew Day School. He is ten years old and I am so proud of him! But Larry has always been somewhat of a jealous person. He would become silent when he thought my eyes strayed towards other hefty men. I never did. I asked him what was wrong and he would say he was tired or he was ill. One day I caught him looking up my email when I came back to get a drink. He was breathing quite hard, concentrating on the headlines of each letter. We both sat down and he revealed to me he was diagnosed with paranoid personality disorder when he was in college. He was on pills but he threw them away after he met because. He said I was his cure and all he needed was me to fight the tendencies. I told him it was sweet but he needed professional help and we got him back into therapy and medication. But it seems he has gotten so use to the medication he is addicted to it. Not in a drug addict sense but in a sense that he needs it to function normally. The psychiatrist and doctor's would tell him to stop taking it for two weeks to see if he got better without it. During those two weeks he would question me about everything and my love for him. During those times we'd take a trip somewhere with our son and that calmed him temporarily until he got back on the medication. But now he has been on the medication for a year, until those weeks when he is off it, and has been attending his sessions which I go and wait outside for him. Sometimes he says when he goes to his therapist, he worries I am with another bear, or a beautiful girl, during that hour so I have to bring our son along to reassure him. He is getting better, much better than when social networking became a big thing (I'll tell that story another time). He expresses his fears of me abandoning him with our son, that one day someone else, someone younger will come along and steal us away from him. But he also swears he'll work to get better, which he has. For the past 6 years now he has taken his medication and followed the dcotor's orders of when to taken them and not. And he has not missed a session. So what I am saying is why is he still like this after all these years? Does he need the medication that much to fight the tendencies? I don't want anyone else, he is a daddy bear, 330 pounds with a burly, graying beard; smart, funny, romantic, what more could I want from a guy? Thanks in advance for your answers. :)
