Will I ever get over this?

[Fmll]

So I split with my ex a few weeks ago after 15 years together and he is already with somebody new (a co worker) I am literally heartbroken and he just seems to have got on with his life. Ending it was the hardest thing I have ever done but he was literally never at home/various hobbies/nights, days out. He has already introduced her to the kids and they have booked a holiday! Meanwhile I am in a heap on the floor trying to process it all.

Honestly, I don’t think I will ever have a relationship again. The whole thing was painful and it should be enjoyable. He has really put me off

Even after we split it is hard work

I am so sorry you are going through this. I split from my ex of 16 years 4 months ago after his affair. Not Married No kids but I lived with him. I had to leave my job and friends and move away and out of his house with only the belongings that i could fit in my car and start again. She moved in and is now living my life. 4 months on I have resettled in a seaside town, it has lots of older people and I have joined lots of social groups to do with my hobbies that I never had time for before. I prioritised my mental health and forced myself to get dressed, eat healthily every day and join a gym.
I am now working and have made some new friends. I no longer feel sick every day and I'm actually sleeping through the night now.
I have put dating on hold and will seek some counselling to help me move forward .
What I'm trying to say is be kind to yourself and allow yourself to grieve for your past and your future that has been taken away from you. I found that the one person that I wanted to comfort me was the person that caused me this pain.
Surrounded yourself with people that care about you and make you laugh. It will get easier I promise,
