Close friend, we’ve know each other for around 4 years. For context, DH and I have been unable to get on the property ladder so are renting, while she’s recently bought her own house.
Friend sent me a text last night with a picture of a flat that’s close to where I live, saying how she surprised that the rent was so much. I texted back agreeing that rent prices were sky high, and it’s hard for people to buy when they’re forking out so much in rent every month. She then carried on by saying that the area is full of “dossers” (it isn’t?)… I didn’t want to bite, as it seemed like she was in a funny mood and perhaps wanted a reaction. I replied that the area DH and I live in seems alright and we’ve had no issues, and changed the subject asking how her day has been. She then sent another message (ignoring what I’d asked) talking about the area again saying god knows why people want to live there.
Feeling a bit 
at the whole situation, and haven’t replied as I really don’t know what to say? DH says I’m reading too much into it and she was just shocked at the renting prices, but I’ve taken is as a dig at me, for no reason at all. Just a bit shocked as we’re close, so I don’t understand why she’d want to try and hurt my feelings/piss me off?
Happy for someone to talk some sense into me and tell me to stop being so sensitive!
