What are the Women for Him?

In the first part of The Stranger by Albert Camus, the main character Monsieur Meursault values women in a special way. 

First example is his mother's death. He is indifferent to her and it seems that he participate in the funeral because of social expectations. We do not know anything about their relationship. He never showed disguest or anger, he was just indifferent. 

Second example is on the page 43. The women that sat with him, because there was not enough room in the cafe(but it does not specify that though), he found her peculiar, machine like. He spend all the dinner time watching her. When she left the cafe he followed her. He was acting like a small child following an animal. He did not recognised his actions as something he should not do.

Third example is his relationship with his girlfriend and the idea of marriage. He is defnatly attracted to her sexsually but when she asks him if he loves her he says no. At the same time he thinks about marrying her. It seems that he refuses to accept his emotions towards her. After their first night together he woke up when she was already gone and "tried to find the salty smell Marie's hair had left on the pillow, and slept until ten." He subconsciously does things that show his love towards her but he would not recognise it himself.

Does he try to shield himself from women? from loving women?
