Suspicion

My live-in boyfriend is always accusing me and questioning me, he is suspicious, jealous and untrusting. He is 13 years younge than myself at 28 and myself at 41. We are both good looking fit people.
It doesn't matter what it is, a look, fiddling with my hands, licking dry lips, whatever, he is suspicious, of my neighbour who is 82 years old!!
we have been together for a year and a half, living together for 6 months, he moved in with me, if that is relevant.
I am getting really fed up with it, most of the time it's pathetic, I love him but I am wondering why he keeps on and on,I don't think he will ever change.
I have heard before, that someone who is always accusing you, is guilty of something themselves.
Please help, I am at my wits end,

Encourage your boyfriend to see a psychotherapist.

His suspicion need not be because he is guilty himself. Unhealty suspicousness and jealosy is very common among men, and is probably an inherited trait.
