Artificial diamond and not fully transparent

[Hopefulinbalham]

i have been together with my boyfriend for 8 months. I am 50 and he is 63. We were both previously married and our spouses both passed away from cancer.
This week was my birthday. On my birthday he gave me a ring which I know he’d
biughy a few months previously. The ring is a dismond eternity ring (that was my preference), It turned out to be a lab diamond ring rather rhsn s real diamond ring.
I looked at his arm (on my birthday as it happened) and realised that he had cuts all along it - I’d never noticed them before and he said they were from self harming when he was younger. He’d always worn long sleeves or held his arm in a certain way so that I wouldn’t see them. This week we are on holiday and he is wearing T shirts.
i have been very vulnerable with him about my past - I had a difficult upbringing, which is the reason he attributes the self harm.
I am struggling with the fact that he didn’t tell me about this - there have been many occasions when I have been upset and he could have told me and also that he gave me an artificial diamond. He does not appear to be short of money.
He owns a house but is letting his daughter live in it and instead rents his own flat. He has suggested that he has indicated to the letting agent that he will not extend the lease on his flat as he will be moving in with me. He kept saying ‘ground zero is approaching’.
Thoughts?

You need to research laboratory grown diamonds.
They are genuine diamonds.
It sounds like you both need to slow right down.

Limited in that their supply was limited by the dealers.

Why on earth anyone would want to own something that is produced in appalling conditions and dealt in such a way I do not know. Lab diamonds which are identical in composition are the ethical alternative.

Sorry, NRFT, but lab diamonds ARE real diamonds. Just like cultured pearls are real pearls. They're just created differently.

Diamonds: unimportant. Self harm disclosure: unimportant. Unilaterally deciding he’s going to move in with you: massive red flag.

Lab grown diamonds are real diamonds.
I wouldn't even expect someone to buy me expensive diamond rings after only dating for few months. Seems too much too soon.

You sound very petty and you should focus on real problems in this relationship rather then obsessing about the ring.

Have you met the daughter who lives in his house? Not sure I would believe that. I wouldn't let him move in. You sound very grabby about the ring. I think £750 is a lot to spend in a new relationship.

Please don't do this to him. Don't make his history of self harm all about you and how it makes you feel.
It's completely up to him if he feels ok sharing anything about it at all. If he had any idea that this was your response, I'd advise him not to.
