Is it too late to start BD’in this month?

So. I have 28-29 DC. We decided to try properly this month, tracking opk and have ordered a bbt too. Been tracking using opk since CD6. Not had a peak yet (luckily) I explained to partner that from 06/01 - 11/01 (roughly) is important to have regular sex and we agreed best to BD on 3rd,5th,7th, 9th, 10th, 11th, 13th & 15th just to cover all basis.

He said he was too tired on 3rd.. we BD on 5th. Then he made implications he wanted to pick up on the 6th the missed day, but then watched tv until midnight and then said he was too tired.. I spoke to him 07/01 and explained we have such a small window each Month.. so he was like ‘yeah okay I get it, let’s have some fun tonight’ .. he sat up on a zoom meeting until 8:30pm, I did him dinner. By 10pm I offered him a bath and he declined, sat downstairs watching TV.. he came up at midnight, showered, got into bed, laid there awkwardly for 20 minutes complaining of a tooth ache and then said he had to go to sleep as he has a client at 7am..

I’m downstairs. Deflated. Feeling stupid for being upset.

Am I being too sensitive or is he being a real selfish asshole for buying these opk and bbt and telling me we can properly try.. after he has wanted us to wait and wait and wait for past 8 years.. and then avoiding sex when he knows this is our fertile period..... is it too late to start BD’in tomorrow and just hoping it’s enough? Or is there any point?!
