In any marriage ― even the strongest, happiest ones ― problems and frustrations will inevitably arise.

And while it’s not worth broaching every single little grievance that grinds your gears (e.g., Your partner forgot to wring out the sponge again? Annoying but you’ll live), there are certain problems that really shouldn’t be ignored.
Some issues, like abusive behavior or a major breach of trust, are generally regarded as obvious red flags. But other issues that may appear harmless in comparison could actually be cause for concern.
We asked marriage therapists to reveal some of the more subtle but potentially serious relationship red flags that you shouldn’t write off.
1. You feel anxious when you’re around your partner or before seeing them.

Relationship stress can take a toll on you physically in a number of ways: frequent headaches, stomachaches, or difficulty sleeping, to name a few. If these symptoms seem to pop up when you’re with your partner or in anticipation of being around them, it could be a sign something in the relationship is amiss, said marriage and family therapist Jennifer Chappell Marsh.
“Sometimes, if something is off in a relationship, we may not be able to pinpoint it but our bodies will tell us something is not right,” she said.
2. You feel lonely even when you’re together.
