'' And do you think that maybe if you really wanted it you'd do it regardless and deal with the consequences regardless and not spend all this time weighing up the pros and cons? ''
Yes, this statement stood out to me too.
gillybean2 - with all due respect, this sounds like a comment from a person who is a single parent by circumstance, and not a single parent by choice. It also is a comment from a person who achieved a pregnancy perhaps fairly easily and in a 'normal' way (within a relationship) - not someone who has gone through months (maybe years) of consideration, planning, research, interviews, procedures, etc.
OP - If you have a baby on your own (with donor sperm), or if you adopt (which I have never done) - any potential parent is interviewed and assessed for their suitability as a parent. The clinics and agencies are required to do this as part of their responsibility to the child before they can proceed. While I've personally never heard of anyone being turned down, i'm sure it must have happened.
They want to know you've thought about this carefully - from an emotional, financial and practical standpoint - and that you are proceeding for the 'right' reasons. (And yes, it is ironic that many people can and do bring dc into the world without any planning or consideration.)
OP - you are doing the right thing to consider this carefully. As a next step, start doing some reasearch into how you would proceed - where you'd go, etc. Look into what you'd need to do for NHS help, and if you would consider a private clinic. There is alot to find out, and you can use this time to do research. Perhaps that will help you decide if you want to move forward.
