1. No trust

One of the worst relationship deal-breakers is a lack of trust. While trust takes time to develop and get stronger, if you want your romantic connection to flourish and be sincere, you and your lover need to trust and respect one another.

When interpersonal trust is insufficient or is completely missing, it guarantees a harsh and frustrating future for both people involved because it makes you second-guess everything your S.O. says or does.

For instance, if you don’t trust your partner when they say that they will come home later because they have work to do and you start thinking about all of those weird scenarios that they might be cheating on you with one of their colleagues, that keeps you from being confident and happy with your partner.

I don’t know where you stand on this one, but in my opinion, if you can’t seem to trust your partner and you’re always in doubt, it’s one of the worst relationship deal-breakers, and you should do something about it ASAP.
