Non committment

My partner, who I have been with for 2 and half years is very jealous of me. A few years ago I had no money and started busking to make ends meet. Now I have a career as a music tutor, which I have carved out from thin air. I also was getting rather well known locally as a musician, andbeing invited to join various bands. My partner is a guitarist in his own right, and is a very talented songwriter. I have never told him any different. The problem is that people kept comparing us, and would say things like 'You are a good guitarist but she is much better'. This has not helped. I have always told him that I am no better or worse than him - I just know different things to him. He is now at the point where he will not discuss music with me, he treats the word music as a profanity, and equates me to being a musical paedophilic prostitute - I teach children how to play the guitar and I get paid for it. This musical insecurity of his has now filtered into other areas of our relationship. He is always telling me that I don't love him - even though I tell him I do, and now has told me I am a lousy kisser and not good in bed. He has an extremely high sex drive for a man his age, and at my age - 47, I am working flat out, menopausal, and I get tired. Is there anybody out there who can offer advice about this? I would greatly appreciate it. My own thoughts are that he is jealous of the time it takes for me to run my business and he doesn't like the fact that I meet people of all ages and get on with them. He, however, has all day to himself - he is retired - and does nothing but lay in bed, play his guitar, read papers, and watch television. He says his state of isolation is due to the state of the world and how much he doesn't like it, but then he has a go at me for getting on with my life. Please help
