My probation officer says i have to reside at my mothers house, but i have no cerfew.?

about 5 months ago i had a Beautiful baby boy. when i became pregnant i told my probation officer who up in till that time over the 5 years i was on probation i seen once every couple months when he called me to come in for an apt. when i became pregnant he began making regular appointments with me, called FA CS on me, and referred me to many programs, that were not needed but i co-operated and when to every one and completed them hoping for the best in the end. When i became pregnant i turned my life around, but it has been hard my probation officer says i have to reside at my mothers house even though i have one everything he said i have to to prove myself. He keeps saying he is going to send the cops looking for my and if i am at my boyfriends house in the middle of the night i will be arrest for a breach.I do sleep at my mothers house nothing would come between me caring for my child, however my boyfriend just lives downstairs and I do not have a curfew. if i did sleep over that is not considered residing could he really get me in trouble? Also he slanders me to FA CS stating "his worries" and about "all of our domestics" , the thing is my boyfriend and I have NEVER had a domestic. We hardly argue let alone get into domestics. These lies put up many barriers in moving forward in my life and providing the best possible life for my child. Is what he is doing legal.
