Why do you feel you HAVE to go back to the dating scene (for the sake of having a family)?
I hope my story offers some insight...
I was married from early 30s until 36 (incompatible/different long term plans), so we parted as amicably as possible. I dated aggressively from 36 until 37 (I realised it'd be really difficult/impossible to find someone who I fancy/wants the same things as me (family)/at the same time without compromising)...I stopped actively dating and met someone online who I had a situanship with from the ages of 37-39. Really got on/loved each other but there was no future (he was younger and not interested in having a family at that point in his life). Before meeting him, I'd started having ideas about solo parenting... so last year aged 38 I did fertility tests to see what my fertility clinical picture was like: it showed surprisingly good ovarian reserve apart from a blocked fallopian tube. So I did IUI (intrauterine insemination) with a sperm donor and it didn't work. Took a 6 month break and fast forward to Feb this year, aged 39, I did IVF with a sperm donor and was very fortunate to find out that the treatment had worked the first time. I'm now 32 weeks pregnant and all going well, due to give birth in Dec. Chances of conceiving with IVF for my age group were less than 30%. I was very very fortunate. Costs wise I spent around 7/8k.
I simply couldn't do any more dating - I totally understand how you feel. The period between 36-39 was the most depressing/despairing time of my life. I absolutely hated the rinse and repeat cycle of dates/disappointment/do it again and again etc. And time was just slipping by further and further. Though I enjoyed spending time with the person I had a situanship with, I knew it was still wasting my fertility time...I was also buying a flat/changing jobs... I'd frequently sit and analyse my life choices, where I'd gone wrong, if only I'd given that relationship more time I wouldn't be in this situation now etc etc. I genuinely felt I'd messed up and would remain childless not by choice.
Now that I'm pregnant, I feel different when it comes to dating because that panic and dread are no longer here. I will get what I want - presuming all goes well with the birth - so when/if I date again I'll be looking for someone for me/not someone to procreate with/be a pseudo-daddy to my child. There will be no time pressure. I feel very much in control now.
I'm really tired of hearing that women's only options in relation to having a family are 'keep dating ad infinitum' sometimes coming from single people or smug couples who have no idea what inline dating is like.
Many people don't find a partner - the apps are designed to keep us trapped on there as long as possible and keep making them money otherwise they'd be out of business. Dating is emotionally exhausting/ can be financially expensive and can erode our self esteem beyond belief. Most people I know didn't meet on the apps but via more organic routes such as school/university/work/nights out. At 36 I'd long stopped having these options (school/university) I didn't particularly want to mix work and dating (I never met anyone I found attractive at work anyway). The more you date doesn't equal to better success.
Finding a partner isn't a meritocracy exercise. There's no formula to it. And I did everything 'right'. Discussed my wishes early on dates about what I was looking for etc. I was also feeling so lonely as have no good family/friends support network. Dating was pure hell for me.
Sorry for the rant! If you wish to know more about my solo parenting route PM me, otherwise good luck with whatever you decide.
