Filly, I want to share with you how a family members life developed after her husband of over 30 years had an affair with her best friend. Her ExH left her and moved in with her best friend and neighbour.
He simply moved into a new life, one door down the road. (that is lazy AF affair-ing right?) The houses are freestanding, so when she sat in her kitchen, having dinner, her view was straight into the OW living room seeing them together every day.
She was without a career or job, her best friend was the OW and her kids were teenagers and busy with themselves. She was without support and kind of fell apart. The ExH threatened to take the house from her, and thats when she kicked into to action - first she found herself a SHL and kept their house. OW and ExH moved away from next door eventually.
She retrained and had a career quite late in her life. Her bussiness dis really well and she was able to support both her kids through university, whilst ExH wiggled out of financial responsibilities.
She rebuilt her life and I don't think it was easy, but she did it.
Now in her sixties she travels with her kids (we do 3 generation family holidays once a year)
She also travels alone - she joined a senior hiking group and they hiked up the Machu Picchu. She goes on little weekend trips with her grand children. She visits us in the UK regularly, she loves her city breaks!
She recently got a dog and she usually goes everywhere on her bicycle and the dog runs with her. She loves gardening and cooking and I feel she is quite busy all the time.
She also has new relationships but I think she simply has shaken off the firm idea that she 'needs' a man - something she believed in before.
She built herself a completely new life, and whilst I'm sure it was very hard then, she now seems very happy and fulfilled.
I know you can do the same, you sound strong and lovely and you deserve much more than that git of a husband.
