I have written and deleted everything about my life for the last 10 years.
Welcome to our board.
I know when a person becomes involved with someone at a very young age they don't get to experience the same things as their peers who didn't have serious relationships. If your children are very young you have a lot of demands on your time and energy - their needs get put over yours.
I wonder if it would be helpful to you to find a way to socialize with other mothers whose kids are the same age? You may be able to connect with those women in a local playgroup, place of worship, the YMCA or YWCA, or the local Boys and Girls Club. Check the phonebook for possible information or lookup your local United Way website and see what organizations are listed there.
The thrill and commitment of young love and parenthood can only sustain you for so long. Sounds like both of you need to find ways to expand your horizons. I hope you can do that in some small way with the new year. Good luck.
