My husband’s relationship with his daughter feels strange – I think they could be sexually attracted to each other

DEAR DEIDRE: MY husband has recently discovered he has an adult daughter who he never knew existed.

They are spending a lot of time getting to know each other.

I’ll admit I’m jealous and regularly feel like the third wheel but I’m also wondering if there is something unhealthy about their relationship.

The way they are constantly hugging, the deep way they look into each other’s eyes, it turns my stomach.

We have been married for five years and were both divorced when we met.
