Need man's advice, point of view

I been with my partner ( now ex) for nearly 4 years. The relationship has always been good, anyhow he recently got the sack but told everyone including me the company folded and lost the contract. I only found out when I see a work van out and found out that wasn't the case. It doesn't even bother me he got the sack or the Reason why although I could have a good guess. I do have problems expressing my feelings or to argue with him as I enjoy every moment with him I also didn't want to embarrass him so I didn't say anything for 3 weeks Butttt ok we had a moment and I spurted it out now he's finished it. He didn't deny getting sacked just avoided it and said we're finished and he's felt like this for a while It's been a week now, he's been totally cold , very unresponsive to messages and replies are very blunt. Now another question he is a regular Facebooker and knows that's his Facebook has got us both as engaged still surely if you were 💯 that would be changed or id be blocked or is it a case that if he does that people will ask questions and he'll have to explain to people although I'm sure it can be done descreetly these days. Or could there be another reason. Is there hope, I'm also annoyed with myself because if I didn't say anything we still be good now or so I thought

[I also didn't want to embarrass him so I didn't say anything for 3 weeks] As you'd left the problem for three weeks,this is why your partner became angry with you when you spoke about it again. [It's been a week now, he's been totally cold , very unresponsive to messages and replies are very blunt.] As you know this means the end of your relationship with him,as you say he's now your ex. [is it a case that if he does that people will ask questions and he'll have to explain to people] This is why he has kept facebook at engaged.

It doesn't matter that your ex got the sack, what does matter is that he couldn't be upfront and honest with you about it and blatantly lied to you. After 4 years together, your relationship with him should have had trust and predictability. If he didn't respect you and have consideration for your emotions, then you're better off without him, regardless of what's on his FB. Forget about embarrassing him, rather you need to block him and move on from him without looking back over your shoulder. If the guy truly loved and respected you, his actions would have told you so in every way.

Thankyou , been racking my brain , thinking Im in the wrong , maybe I am 🤔, but only because I hate confrontation I never said anything 🙄
