Intense jealousy after miscarriage and neighbour friendship, will these feelings pass?

[IrrationalLobster]

I’ve developed intense jealousy and don’t know what to do. DP used to be quite chatty with a neighbour but she’s recently become single around Xmas time the same time as I had a MC and I just can’t cope.
DP to be fair has said he understands and my mind is just grieving and it’s probably temporary so he has ceased all contact with her (he gave her a lift a lot of days to school since Xmas with her dc as he does school run) and they used to chat a lot.
She did make a remark to me one day when she knocked to ask to speak to him and I said sorry but no.
I am having therapy but it’s so intense and I’ve never had this before. Will it pass?

No you're the one who refuses to acknowledge that not everyone has honourable intentions.

If anyone is being woefully naive, it's you.

She’s a cheeky fucker op. Bringing DP a chocolate egg instead of the whole family, pushing back when you said no to lifts then trying to go around you and get your DP to side with her over you. AND telling him not to share his egg with you. she’s actively trying to come between you.
Your dp has responded correctly but I imagine she’s going to keep pushing on this, I would assume this isn’t the last. I’m not really a jealous person but I think she’s crossed a line.
