In the precap, Abeer tells Sasha about his son, again I don't think any wedding is taking place here either. I just can't see Abeer going through with this marriage now knowing that he has a son. Sasha herself should take this as a sign, she already seemed to have doubts before Abeer called her. Hopefully she stays positive and exits the show gracefully.
After this episode, I don't even think a MehBeer wedding is going to happen at least not so soon. I feel Abeer will ask Meher for a chance to prove himself and take some time in bonding with Ishan. It will be like his redemption period. This track has so much potential, fingers crossed CVs do it right :)
