Most Helpful Guy
You got back together without solving anything in essence. Am I interpreting that correct? Sounds like a desperate situation without any pause for reflection. You still feel the same way as you did when the relationship split, you're simply suppressing it; exhibiting more control.
The unhealthy bit is you're being motivated by fear and holstering your insecurities. You're allowing your imagination to play on your emotions by avoiding the situation. Sooner or later you're going to blow a cylinder like previously if you keep it up.
