Open episiotomy

Jessica • Race car loving, police dispatching, first time mom to be.
Has anyone had an episiotomy heal open before and had to have it repaired.? Mine healed partially open and I have to wait for it to completely heal before it can be repaired. My midwife said if I don't have it repaired it will always cause me pain, especially during intercourse.
Anyways, I'm 12 weeks postpartum and that's the normal healing time for episiotomy but mine is still not healed so I'm wondering who has been through this or something similar and what was your healing time ?
