Laurie,
I have been in your situation two times!! Widowed twice...once at age 28 and then again at 38. So I really do understand.
The first time I had two young children, 2 & 5...so I stayed home with them and didn't work....they kept me very busy and financially I could do it. I really needed to be with my children those years for them and for me.
The second time I was 38 and had 3 children and all in school so I decided to get a job and it was a very good thing for me. I joined a singles group thru a church and got active and out in the world. The group had meetings at a church and homes and went out to the clubs after meetings to have a drink and mingle, get to know everyone.
So that is where I met my third dh, at a nightclub!!!! He wasn't in our group but visiting from a neighboring state on business........well we are now married 18 yrs.
Maybe you just need to start part-time until all the children are in school and still have time for the football and all the other school activities. Ease back into it and then go for the full-time job.
I had 3 at home and it was a LOT & HARD to do by myself, as you already know.
Just look at the pros and cons....maybe make a list. It might be more important this year to be home part-time with your children....then go for the career, they will need to adjust also.
You will make the right decision, I don't know how much of a support system you have....I didn't have any family nearby either time and you can only rely on friends so much. I think I remember you have some family close by so maybe you could do full-time.
A part-time job could just be your stepping stone, don't look at it as a permenant position .... but if the inner you is really wanting that full-time job to be fullfilled....go for it.
Wishing you the best, Phyllis
