@lookame - our story is almost exactly the same! Got pregnant and BF and I got married, big mistake. He was lazy, selfish, couldn't hold a job and drank every night. I finally told him it was over when our son was 18 months. He left town and I moved in with my parents. My current hubby asked me out at work about a month later, and we moved in together shortly after that. The fact that I had a toddler, and Crohn's, didn't bother him in the least. We've been together 7 years, married the last 4 and we have Ewan, 8, and Tamsin, 4. My husband always introduces them as his family or his kids. He has NEVER singled Ewan out or used the term step-son. Now that is a keeper.
As for the Crohn's, he had no idea what it was when I told him. Now he is the one making sure I'm taking my meds, asking me how I feel, lecturing me when I eat something he knows I shouldn't, and takes care of the house and kids when I'm not feeling well.
@jaggartini - my Crohn's went into remission with both of my pregnancies, it was amazing! We don't want anymore kids, but if I could just stay in that state without having any more babies it would be awesome!!
