Sending you hugs, I really feel for you.
My DH and I were also up to the eyeballs in debt and were ONLY just breaking even and sometimes going backwards.
We were terrified. But we calculated that if we waited until debt free or until we were in a better position we’d be waiting for years on end, and he’s ten years older than me.
So, perhaps recklessly, we went for it. I was very fortunate to breastfeed until she was almost 2 (no bottles/formula/sterilising costs) and we still bedshare now (no cot!). We got almost everything second hand, except for the odd treat of a lovely baby grow! Ask around any friends and family who’ve got young kids. We found many were desperate to get rid of stuff and our lo is almost completely clothed in hand me downs (through choice - I LOVE that her friend/cousin/aunt once wore that outfit!).
It was hard at times, and we had some struggles. But I would do it again in a heartbeat. I also found that many of my family said (when I mentioned financial worries) that somehow babies just work themselves out... and they really do.
So I guess what I’m tryibg to say is, please don’t despair. No matter how desperate it might seem. I highly agree with pp about going to citizens advice, they were incredibly helpful for us.
On the flip side, you’re younger than we were, which may affect your sense of how much time you have.
Best of luck with whatever you decide. FWIW, I think you should include your partner in this. Tell him the news and tell him very openly about your fears. Your decision is based on your joint situation so responsibility for whatever you decide shouldn’t have to be yours to bear alone. Yes, he might talk you out of an abortion, but that might be because he can see a way through it.
My last thought, there’s probably no wrong decision here. And it’s an awful one you have to be making. There could be regret on both sides of the coin, but whatever you decide will be the right one for you.
