S response to your asking him about it got cut off here. I don't think you're wrong to have "alarm bells" sounding, but I'm not sure you should jump to conclusions right now either. I'd think someone old enough to be married for 20 years would be too mature for "text flirting", but I suppose some people "join in" with what younger people do.
On a separate thing, it's kind of too bad he knows you were going through his phone; because that could potentially make you seem to "nosing around" in his personal business - never something people like. Then again, if he leaves the phone around and makes no effort to keep it to himself, maybe he doesn't feel he has anything to hide.
I don't think you're wrong not to be "too thrilled" about it, though. Sometimes when someone knows s/he is guilty of something s/he tries to make the other person feel wrong. You're not wrong.
Smily faces and "hi" are one thing. "Can we be friends" and Valentine messages are another. I don't know what I'd do in that situation - just wait and see what unfolds (maybe through calm, reasonable, conversation).
If you're married to this man what should've made you do an about face was his texts to another woman, not one thing in particular.
You're NOT making a big deal, you need to put things in there place and have self-respect.
Text flirting... lol serious some people require attention and sometimes they feel good about them selves when they think someone may be interested in them and they have no attention to do anything other than joke and have fun, if it was the other person saying something about meeting, I would disreguard it as spiritual play. However, with him initiating the question about meeting that is questionable, the valentine thing is cute and a friendly gesture and all-in-fun no matter who it is sent too. I suppose it depends all on the situation and I wouldn't hound the issue at the moment just be cautious and let him know how you felt about the text and see if he doesn't repect your feelings or how he reacts.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
