I left my husband when my kids were 5 and 7. I didn’t date for 4 years. I was more focused on providing my kids with stability, routine and of course the emotional effects of not having their father full time. The idea of having someone in my life was nice but knowing my time and focus was limited meant that whoever that person was would have to be patient and understanding. If you really like her, be patient and understanding but be clear about what your intentions are because if she doesn’t feel like this has potential, there’s no sense in getting involved romantically. It’s not fair to you if she’s just keeping you around for stolen moments because she’s lonely at times and it makes her feel attractive, desirable blah blah. If you don’t want the same thing from this then it’s best to move on. If she just needs patience to see where it goes and is interested, give it what you can and nothing more.
