He hates my son

[Helcl]

My partner of 12 years had a couple of drinks and told me he hated my Son.
I am hurt, lost and I don't know what to do with this information.
I love my Partner but this has really floored me.

With children, it's normal for them to have irritating habits and also great redeeming features. Complete hate is very strong!! And yes the emotion might be more tied up with his own crappy childhood but to project it onto your child is awful.

It's normal for kids to be self centred.

How does your DS feel about your DP?

Your post has made me feel sad op.

I think your dp is a jealous child who has never been properly mothered. He probably hates your ds because your ds is loved so much by you, and it needles him. He may not be able to verbalise even to himself that this is what's going on.

Hi Helcl, it would be a good idea, to take your Son on one side, and have a thorough heart to heart with him. Listen to what he has to say, even if it is hard to hear. You will be far better informed then, and your decision will be made easier. At the end of the day, no matter the previous life problems, of your partner, your DS, must be your priority.
Hope this helps.
