I was engaged to her, and she said she loved me, but I never felt it. Never send me a text message or call me. I sent messages, and she rarely replied that she didn't read them. ...

No, a woman loves a man and always thinks of him. If she's all right, send him a message and make a phone call. Maybe every woman's personality is different, but the reaction after falling in love with someone is basically the same. Imagine, if you love someone, will you not return her text messages? Not calling her?

Besides, you two are engaged, so she should have loved you at first. Maybe after a long time, their feelings will become dull and have no passion. But you can create passion, romance and mystery. Women like romance, so you can do something when you first start dating, which may help your relationship!
