if you do it face to face as opposed to text you can pay attention to his body language, expressions and tone of voice. so it will be much easier to see if he's being sincere or just bullshiting. yes I think you should confront him you don't want to be possibly played.

Honestly. If he's using you, i say use him back, play his game, on your terms. If he is seeing others, stop texting back offten, say your going out with some "friends." Enthuse over other men. If perhaps he's not giving you what you need physically, such as support, cuddles, help. Then refrain from giving him any. If he IS using you, most likely he has a big ego, stop feeding it and watch him starve and start to get a little panicked. But if he's not someone your actually interested in, talk to him indirectly about it. Bring up whatever he's been doing in subtle ways. "You've been hanging out with Jane Doe a lot lately, everything alright?" Or perhaps when he has a rough day "what, want me to coddle you or something? Big ass baby."
But ultimately its up to you, I spend too much time thinking of too many situations that will probably never happen too me. So i've thought a portion of all this out should it happen lmao.
