Psychic shielding and warding of your space should afford you a little peace. Whether or not people intend to invade your privacy/space, they sometimes do, particularly in the case of parents.

(I had to build very specific shields against each of my parents, with their actual names on the permashields, because despite being on the opposite side of the planet, they kept invading my dreams and sometimes sneaking into my personal space when I was meditating or similar. They never did respect boundaries, so I had to forcibly create psychic ones to keep them away. And, yes, it did work.)

I also advise doing tie cutting rituals regularly. This does NOT end a relationship! It does cut lingering ties, but if you're in a relationship with someone, new ties will be created. Sometimes, this has the effect of allowing better and more positive ties to be created (because, face it, even the best of relationships have their weird, non-productive areas, and tie-cutting can help with this).

In your case, I think it could help if the shielding included some sort of "non sight" barrier, meaning, the shield (and protection set up by any wards you place) has the effect of cutting off the ability of anyone to sense your activities. This may occasionally backfire, as they see the lack of visibility as a danger sign (or they just resent being unable to spy on you), so be prepared with the tie-cutting and protection and so forth. But, in most cases, people will just take the "can't see you doing stuff" as "oh, good, you're behaving yourself".
