Like others I would be wary. My ex sent numerous gifts through the post to me. I ignored all but still got an email later (after 6mnths nc on my side) asking me to pretend we were still together and attend his dad's birthday!
On the other hand, I refused parental help for ages but once I felt strong enough, I found a new more balanced relationship with my DPs, and (later) accepted their help and have been able to maintain healthy boundaries.
However! My issue was feeling beholden not that they put restrictions on money given or lent. When I got over that and stopped thinking about my siblings taking help I was ok.
Taking help when we feel vulnerable can often make us feel more vulnerable if we don't trust in the person helping's intentions.
If you feel like taking a step in the direction of reconciliation, accepting the money as a loan (& putting money away to pay back if things go pear shaped) could be a way forward.
Once I'd paid back a loan and 'proved' to myself and my DPs that I could and they showed no interest in controlling that money/me, I felt better about myself, my DPs and my choices about accepting gifts in the future.
It's a hard decision but don't feel you have to be y/n right now, you could be a 'maybe', take it as a loan, take it & save to pay back, take it and nc, take it and low contact etc etc
You could also accept in one form or another but add that contact via work was inappropriate - perhaps create an email just for DP then you could choose when you check it/what contact you have.
I am very happy to now have a better relationship with my DPs but I know that's also because deep down they are good people, you will know your own DP and relations best yourself.
I wish you all the best - not easy!
