Practo user,
Relationships are tricky and unfortunately there isnt any guide or rule book written to understand them. Bullying isnt alright and should be dealt with sensitivity. There is a thin line in relations which shouldn't be crossed. Respect and trust are important pillars for any relationship. With that being said, I recommend that you go in for counselling with this person by a psychologist. Also consult a psychiatrist to treat you for your depression and anxiety. All the best!
