Sounds like new wifey may be laying down the law and he is realizing grass is not always greener. I suppose he's lying since you have seen pics of rings?
To me this shows lack of respect for your feelings BC instead of thinking she blocked me I probably should leave her alone he decides to create a new email and bother you anyways. I be insulted that he thinks he even has a chance after everything. I have learned over the course of last six months that sometimes the best response is no response. If you tell him how you feel and say no he will just argue it. If you don't reply he probably will stop bothering you but if it escalates well I guess. There's always a restraining order.
P.s. don't believe everything you read. Actions speak louder than words. My ex sends similar emails then I check into it and find he's online dating sites looking despite his claims of not doing so and me being the love of his life and how torn up he is.
