We can tell you what we think and what we would (or have chosen to) do but ultimately this is your own life, your personality, priorities and threshold will be different to us.
The way I see it:
- There is no guarantee with anyone that you will have good satisfying sex. Many men are clueless
- Is my exploring dating other men and the headache and drama dating brings to my life worth missing out on seeing my child everyday and struggling on one income? Even if I wouldn't struggle, is it worth reduced finances?
- If the shoe was on the other foot would I appreciate being left for needing to take important medication to enable me to stay sane, alive, well and be there for our child?
I forgot who said, but on page 1 a poster said she will be flamed because she decided to cheat and has an affair partner with rules. Well, that may work for her but I suspect for many women, and I know for myself, I would not be able to enjoy sex with a man I met for sex. I want that bond, I want the dating, the intimacy. I don't want the (unpaid) prostitute sleazy experience, thanks. That's not worth missing my child every other weekend for and managing on a single income, in possibly a smaller and worse accommodation on my one wage.
You can't get everything from one person, I'm of the view that you either compromise or you have an arrangement where he knows you have a boyfriend on the side but realistically, to find a man like that is going to take time away from your family as you date and establish a bond, it will also take mental space in your head when they text or don't text and what does this look and gesture mean ... etc.
The grass is not greener. You might have great sex, but he's not a good dad or has addiction. You might have good sex but then YOU go off the sex.
There is no guarantees about this mystery stud that may or may not come into your life. What is guaranteed is the drop in finances and seeing your child less. Some people make decisions based on facts, some do them based on gut feelings or heart. Just make sure you are realistic about what your life will be like because good sex alone isn't enough to set up a family and home.
