I'm 37 and a half and have no children. Been with partner (41) almost 3 years. We don't live together. He has 2 children from previous relationship (21 and 15). To be honest the relationship has been rocky and unstable for over a year. It's been incredibly volatile the past few months (I never know if we're breaking up or not as he goes very quiet on me for day/s at a time). Our contact/communication has fallen dramatically, he's been making big decisions without really consulting me, I'm on sleeping pills. I am not a saint but I have repeated to him countless times that I want to work on us. I have done a bit of work on myself and still attend the relationship counselling that we started attending together (he decided a few months in that he didn't want to continue it). We are now at the stage where he is barely responding to my texts, and if he does it can be the day over 24 hours later. Breaking up has been brought up multiple times; I last asked him this at the weekend, straight out, he gave a long pause and instead we are meeting tomorrow so he can tell me his needs (I had told him mine a week or so ago), though tbh I don't know if he's just wanting to end it. Whether he does or not, I'm very keen to have a child (he has known this for a long time and we had intended to have a child together though tbh I seem to always have been more invested in the idea than him, as he has 2 children already), but because of my age I am getting some eggs frozen in January, as a 'back-up'. He knows this too. I'm now strongly considering getting them fertilised by sperm donor at the same time. Partner knows about egg freezing but we have not yet discussed my option of getting a sperm donor at the same time. I have not made a definite decision on it, as ideally I had assumed we'd be having a child together but given how volatile things have been, it is a big risk for me not to take as my time is fast running out, and this may be my only chance of having a child I know I must tell him tomorrow. I plan to explain to him again how much I want a child. And repeat to him that my desire to have a child, whether with him or not, is so important to me. I am very bad for overthinking and gaslighting myself and would appreciate thoughts on this.
