How to revive my relationship with my boyfriend which had suffered due to my dad? Should I tell him I have a cheating father?

Hi everyone. I would like to ask you all out how would u have recovered from your past and rejuvinate ur relationship. I have a cheating father and he had been cheating my mom since as long as I know. I'm an Indian girl and in my community divorce is downseen. As I saw my dad cheating him since I was a child, it's very tough to rely on my boyfriend and trust him. Although he had never cheated me or never made me feel down, but it's very tough to trust anyone in a relationship. Hence, it has severely downgraded our relationship and in this lockdown it's becoming very tough to revive. Pls help me.
