Hi Brasucasulu

Well I'd say..........what is wrong with disliking him???!!!
It's not mandatory or an expectation to like any particular person.
You like and dislike whoever you like and dislike..........and with him, I'd say that it's completely understandable that you don't like him...........afterall you can emphasise with someone close to you the effects of his unacceptable behaviours, and you can see the impact on his wife of his unacceptable behaviours. Being someone's father or husband doesn't give you the right/the entitlement to behave the way he has/does.
So I, personally, see no reason you should feel guilty about the way you feel.

And if being around him makes you feel uncomfortable then maybe talk to your BF about how he'd feel about you minimising that contact. I don't know whether he might want you around a bit for some "morale support" when he sees him, but maybe you two could find a solution that you both feel OK with??
And, if needed, when you are around him, if your BF wants that..........just aim at being courteous.........nothing more??

Just keep your focus on the relationship you have with your BF..........that's the one that really matters, right??
