YWBTBF if you actually did the passive aggressive thing. anything else, from fantasizing about doing it to finding a direct way to tell him you're upset is solidly NTB.

honestly, it's only been three months and i'm of the mind that the first 6 months is far too early to be dealing with any kind of big bullshit (big bullshit being stuff you have to ''work through'' like infidelity, addictions, etc). 3 months into this you should be happy and blissful AF and he shouldn't be even looking at other people.

it is definitely NOT the time to stay and work on things after 3 months, or play off your concerns as ''trust issues'' or ''insecurity''. staying and working on things is for couples with a solid foundation of trust and commitment. stuff you have to ''work through'' 3 months in is just incompatibility or a blazing sign that it's not going to work out. the reason you're ''insecure'' is because part of you knows that in a new relationship, you should be priority #1. that's not pathological, that's your brain telling you that this is some bullshit.

always remember that the beginning of a relationship represents the best it can be. only stay if you can handle it going downhill from there, even if only a little. if you're not happy (or if present issues dull your happiness) when love chemicals are blasting you with happy-crack, it's not getting better.
