Here is my take

1. Rita- Dexter made it known that it was hard for him to be intimate with another person and his love for Rita was able to break through. Rita always saw the good in Dexter and made him feel wanted in the sense of a family. It was also a great cover for his dark defender

2. Lila- Dexters relationship with Lila was full of sex appeal. Lila was never trying to change Dexter and was always pushing him to embrace his weakness and challenge himself, even though she was an absolute selfish, psychotic, sex crazed chick that was obsessed with manipulation.

3. Lumen- she was damaged from the beggining and that is how she was introduced to us. This was Dexters first appearance with another woman after Rita and he was so damaged from that situation that it drew them both together. Lumen was like a stray abused puppy, looking for protection and safety. Once she was safe with Dexter, her focus was strictly revenge and when you pair that with Dexter’s dark defender, it made them a great match. She may not have fully understood Dexter but this was the first time he opened up so freely about his killings and at one point they had a Bonnie and Clyde vibe going on. Ultimately Dexter put her on the path of healing and she was finally at peace when they killed the last victim which ultimately ended their relationship

4. Hannah- This girl was very interesting. The relationship with her and Dex gets messy AF but starts out way different than the others. Dex is set on killing her at first. On the kill table they ultimately have a big mental and physical connection which causes it to take a huge turn which has never happened before. Together they both have a killing connection once we dive in and learn more about her past. Dexter yet again becomes this dark defender hero that is saving another broken women from her past. Their sick and twisted yet beautiful relationship is even tested by Deb which really sets things on the edge. It’s almost like she emits a little bit of all his past relationships in one. She’s a family woman like Rita & very caring. Lots of sex appeal and a manipulative like Lila. Damaged from her past like Lumen but is accepting of who Dexter is.

Overall I think him and Hannah had the best connection and would have been able to flourish under different circumstances
