My mum has blessed my sister’s relationship with my ex despite them dating months after our split

DEAR DEIDRE: MY sister has started dating my ex just months after our relationship ended. I don’t want to go to my family home now because he might be there.

I don’t want to see him or speak to my sister either.

I am 25 and my current boyfriend agrees with me that my ex and younger sister have no class.

She is only 19 and my ex is 28.

I split up with my ex six months ago because he was always messing me about.

We were together for two years and I have since moved on. My ex is not a patch on my new boyfriend.

Maddeningly, nobody else in our family sees an issue with this. Even my mum has blessed their relationship and sees no issue with the age gap.

I am appalled that they can welcome my ex into their home as if nothing has happened.

The whole situation has made me feel ill at ease and I’m very unsettled by it.

DEIDRE SAYS: I understand your concerns. Age-gap relationships can work but your sister is at a completely different life stage to your ex.

Also, while the law considers your sister an adult, the reality is she has a lot less life experience than your ex too.

My support pack Age Gaps – Do They Really Matter? explains more.

Unfortunately, there is little you can do if everyone else has accepted their relationship, except for focusing on your own life, which will give you less opportunity to be upset by this.
