Spoiling my life day by day pls help

Hi. I don't how to explain my situation but i am writing something hope you will understand.

I am 28yrs old. I am getting married in May 2013. Before this i was into 2 relationships which couldn't succeed and i don't regret about it. Now a new gal is in my life and I am going to marry her.

She is not in my city and we talk on phone everyday. She is very calm, but i am very rude while talking to her and get angry on her everyday for some or the other reason. The reason behind my aggressiveness is that she and her father talked about her brother-in-law every time during the beginning of this relationship. I feel like I am being compared. I am not able to tolerate this. I have told this to her and she said she wont do it again. but i am not able to forget this.

Even though i am not in touch with her brother-in-law, I don't want to meet him nor attend his family functions this is making her sad as we are one family. I am not happy when she is sad. I am ruining my days like this. I am avoiding her and don't feel like talking and meeting her. She says she would die without talking to me. I feel restless. i get annoyed and cry sometimes. She doesn't understand my problem. Please suggest what should I do. How do I go with this relationship. I am also attached to her and cant imagine my life with out her.

Thanks in advance for your replies.

Hi, welcome to the delusional disorder forum. I am sorry that you are feeling badly regarding your relationship. I noticed you are in your twenties, I mention this because this condition tends to set in later in life...

Are you worried you may be delusional?

As with most people who feel emotional turmoil I'd recommend seeing a trained mental health provider, but listen to what your emotions tell you.

Best,
Sunny
