OP, be proud and very gentle and loving with yourself.
This perspective - the stereotype of a Jeremy Kyle guest - is deeply misogynistic. I have had people say to me that they "never would have imagined it of me" (!) when they hear about my family set up.
It is similar to hearing : " I'm not racist but..." or : " I don't really consider you as black, you are just you... which 2 of my DC also experience ...
Ignorant and judgemental , even if only thoughtless and unconsidered.
I have five children by three men. I was married to two of them, but they left. This first when I was pg with dd2, the second when dd4 was 2. I wanted both of those marriages to work , and to last.Both exh's have been sporadic with contact and money, and have gone on to live life as single men ,doing whatever they want.
Dd5 has no contact with her father, who became violent when I was pg, although no previous signs. I had thought that we were going to have a settled relationship, as did the older dc.
I have maintained ft professional career and mortgage and do all I can for my DC. I have had other BF's since, but would never marry or even live together again.
Who is the "Jeremy Kyle guest " in this story? Not me, and not my DC.
It is deeply disappointing and very hard work. But absolutely nothing to be ashamed or embarrassed about.
