I've never deliberately 'tested' someone - I've been 'tested' by a couple of boyfriends in the past myself, though. To be honest, I found it very manipulative and sly and it was unpleasant to be on the receiving end of it. Ironically, both those boyfriends were themselves abusive, one emotionally/psychologically and the other physically.
Obviously I'm absolutely NOT saying that the OP is being abusive here! Just that for me, just personally and because of my own experience, 'testing' would be a red flag.
I do think there are situations that just naturally occur in the early days of relationships that give you an indicator of whether things will work, but it's more of an organic thing for me, not a situation where I would be 'testing' the other person. For example, if I went out for a meal for someone for the first time, and they were an arsehole to the waiter, that would be a red flag - but I would never think 'Hmm, I'll suggest we go for dinner and then I can watch him to see how he behaves to the restaurant staff'.
That's in no way necessarily an indicator of domestic abuse but I personally can't be with someone who gives the silent treatment if I rib them about the football
See, for me, if a partner 'ribbed' me about something that I didn't find funny, and then got annoyed/upset when I didn't give them some kind of reaction, THAT would be a massive red flag! I can't stand people who like to bait others for attention (especially about something that's important to them) and then get annoyed when their target doesn't rise to it. My boyfriend's team have been relegated more than once during the course of our relationship and I wouldn't have ribbed him about it because while he wouldn't have reacted angrily he also wouldn't have found it funny - and exactly the same would have applied to me when my own team lost a massive final a few years ago.
Again, I'm absolutely not saying you are being abusive or horrible - and I think 'silent treatment' and 'no reaction' are probably two different things anyway - but basically what I take from this thread is that there is very much not a one-size-fits-all solution to relationships!
