Is it wrong to love my cousin

Hi there,I'm dennis .This is my story loving my cousin.
I've met her through a family reception. she was so pretty and never saw a girl so beautiful. it started when my aunt asked me to go buy some grocery at the supermarket. i did not know the way around their neighborhood at that time, so she insist i take my cousin with me. so we stared talking and stuff. it became very often that my cousin keep visiting me with her father and mom. we would talk for hours just about anything at all. we have allot of pics together just hanging out.

we got closer to each other until she started to fall in love with me. she keeps telling me how wrong it is. but i told her, that i love her too. we started to kiss and touch each other. we did not had sax that time cause of everyone around. It happened on my uncle's birthday when i asked my mom if i could sleep over. It was all in our plan what we would do if we were ever alone.
the night came by till everyone went to sleep , and i was alone with her. she was amazing and beautiful. we talked for hours, hugging each other. she sead that , she was not ready to take it this far and how wrong it would be. but i was so ready to make love with her and keep telling her that i don't wanna miss this opportunity again, we should just let it happened. so we had sex. next day in the morning we had breakfast and talked about how a good time we had. it was till that day , she keeps avoiding me and telling me, she needs to stay away from me before things wrong.
we both have strict parents and it would be very bad if they know about us. and so she stopped visiting me less often than before. i still had contact with her but it faded slowly away :( . i now moved on and got married a few years now. she came for my wedding with her family and was very supportive of my decision. but i never heard from her again.
As years pass by i miss her and even dream about her.sometimes i just go back and look at our pictures together. i try to message her so many times back but she had only reply to some. i love my wife but i just want to talk to her again just even as friends. but she would not reply again . i had to share my story cause i can't talk about this to anyone here. should i keep trying till she reply one day or just move on.i would like to hear from you all with i should do. thanks for reading.
