Do you think after the kiss of Cordelia and Wesley they ever had feelings about each other. Especially after graduation.

I think that they were very attracted to each other at first. Almost like a forbidden attraction. He was an adult and she was still in high school. But once that wore off and they kissed they found that there was no chemestry. You can be attracted to someone and have no chemestry with them. Also I think she needed a stronger man.

no because they saw each other in angel and there was no sparkage

Haha I laughed so hard when they kissed..it was liek you expected it to be this magical moment you had all waited fo rlike with Xander and Cordelia but instead, no music in the background, Wesley is croushing down slightly to meet Cordelia's height and you can tell just by looking that neither of them is enjoying that moment....It was extremely well done
Joss Whedon is amazing!
But to answer your question, no I don't think they had feelings for each other, I think Xander was more of a man than Wesley, plus they basically give each other a brush off after the kiss and never speak again... so if they did have feelings it was extremly unapparent and not meant to be noticed

Before the kiss I think she had some feelings that he was a confident, smart and brave man. I think that kiss was so bad that she felt she was kissing her brother. It was funny that Joss made them try a second time and that was just as bad!!! After the bad kiss I think they both knew that it wasn't ever going to happen again, ever!!!! After graduation Cordie actually killed a few vampires while Wesley in two seconds was hit to the ground and stayed there. Even when she saw him in Angel she started to laugh at him!!!

i think in angel he lliked her but she did not i think it was all about xander cuz it made him mad so she thot she liked him

No, they never had any romantic or sexual feelings towards each other after that awkward kiss. The kiss was actually put in to close off story of their attraction before they interacted again in ATS.
