Thank you for your reply

I have suffered post natal depression but I've
since had therapy for it and i feel that it's not a factor anymore.Also, we
had problems long before she came along, the reason why it's worse now is
that i really changecd after having my daughter. i felt huge resentment
towards him being able to go back to a "normal" life whereas i felt stuck
at home and lonely and going through a complete life change, i then started
to really behave like the "real me" which i had never done before, i have
always tried to be someone else with him, and to try and please him and be
who he wanted me to be, but now i know i'm being me and this is what the
problem is - we are completely incomaptible

I am 100% sure that things cannot be resolved
between us, because essentially, i do not love him anymore.
i think
he really believes that all the issues in our relationship stem from my
depression, it's like he's waiting for me to go back to how i was before I
had my daughter but I just can't. I'm not prepared to live a lie
anymore.
I feel like this must make me incredibly selfish but I know
if i stayed, i would never be happy and my daughter would be affected by
this.
