Jennifer Garner’s boyfriend has no qualms with ex Ben Affleck: Source

John Miller is not trying to push Ben Affleck out of Jennifer Garner’s life, despite Ben spending a lot of time at her place. John has been patient and understanding, endearing himself to Jennifer. Ben has a key to come and go as he pleases, and has been spending time with Jennifer and the kids. Although John is not trying to force Ben out, the constant presence of Ben in their relationship is becoming overwhelming. Ben and Jennifer are working on a movie together, which has caused some tension. Jennifer has reassured everyone that she is committed to John, but he understandably wants to see some actions to back up her words. Ben turned to Jennifer after his split from JLo.
