we have been together for 7 yrs have a 15 year DD (step daughter to DP) a 2 yr DS, and pregnant with third. we are both 35. I dont actually want to force him to have aVasectomy I realise its his choice, but I felt insecure when I brought it up as a possibility and he said he didnt want anymore children but what if I died/or we split up and he got a new partner. his answer made me feel scared and insecure and ridiculously jealous! , I told him this he felt sorry but that was his true feeling about the issue.
