Certain habits (mostly based on frequency) can push away a partner. One of the biggest is criticizing the partner frequently.

Another barrier to relationships can be if one partner is less emotionally communicative than the other. However, by the same token, being distant when a partner is communicating distress can also destroy a relationship. Complaints, if important, should not be ignored, because if someone feels strongly enough to bring up an issue, it should be addressed. Finally, and related to the previously-mentioned lack of empathy, don't let screens and technology distract from communicating.

Key Takeaways:

• 80 percent of what you say to your partner should be positive and only 20 percent negative, not the other way around.
• When one partner is better at verbal communication than the other, this gives the verbal partner an unfair advantage during arguments.
• Too many couples are focused on their phones and other technology when they should be paying attention to each other.

"when they become habitual, they can go from irritating to damaging in terms of relationship satisfaction and longevity."
