Is intercourse a way of taking back my wife during her Iddah?

Asalaam alaikum warahmatullahi wabarakatuh, About a month ago my wife requested a talaq from me due to pressure from her family and a month before that they instructed her to fetch her belongings from me and move in with them. After 2 months of no contact we started communicating and had intercourse after her visiting me. In the visit i could see that she still loved me and was still inlove with me as we discussed the reasons she left me. On another occasion due to the passing of a close friend I collected her and attended his funeral. Thereafter we had intercourse again, but with intention to reconcile. I have arranged 2 witnesses to draw up a document to revoke the talaq and take her back as myself and my wife agreed to reconcilation and I would rather take her back in all ways possible as I am afraid her family would try and find ways to keep us apart. **Is intercourse a way of taking her back?** Once I have taken her back with witnesses can her parents keep her away from me? She will not be present but she is aware of me revoking the talaaq, is that permissible? Shukraan in advance for your assistance.
