Hi Ravi, I am currently in relationship of almost 7 years but after the COVID there was some conflict or no contact with my partner just because of a scenario. I always used to order some food for her at his flat. Let me clear one things we were in a long term relationship that time. So I ordered food and she got the order then called me in the night with a different voice tone, I said yes then It felt odd. Then she said someone is here I will call you back. Then she didn't so I called her after 2 hour she rejected and after sometime messaged me on whatsapp that deleted everything our chats and conversation because she caught by his brother (who is 10 years older than her), she told me to not contact her she will call or message only. I got scared I deleted all chats because her brother is so rude and arrogant. After 10 days she called me and said we are not going further with this relationship now on we will not be in touch, I was devastated by listening these things so I tried my best to make her understand that I will talk to your parents or brother but she denied NO and said I will again talk with bro. After these scenario she tried not to contact me and I kept trying to reach out to her via messanger because she has blocked me from everywhere. I cried alot in first 2 month then I started to link all those things that she said and try to find out the matter ( note - she got lot of friends) so I found that she in her flat then I got the tickets and go there to see what is happening I waited for the whole day then in the evening I go upstairs and open the doors, she got scared h and stunned by seeing me and I saw a guy in the flat they having hookah then I said give me my stuff and ask her to talk for the final tine 10 min downstairs. She said not now then didn't came. I took my stuff nd leave the next day I tried to over come this situation nd reaching out to his bro but didn't get connected. She also called me the next day nd her frnd but I was not able to talk. After we got disconnected for sometime. And I am a person who always wanted to know the truth behind the things because I can't live with these traumas in my mind so I tried contacting her asked lot of time why did you do that nd all but kept denying that he is just a friend. After sometime on day she came with sone massages nd saying my mom is not good nd there is nothing going well in my house plss sorry nd all so I took it normally but after sometime we got attracted again little bit then realise that we can try atleast once to be together. I know she loves me but I don't like her priorities she always put his frnds over me. Idk what to do pls tell me the way to cop up with this thing. Also I still have in mind that she has something to tell me about that boy but not telling me.

Thanks Madam, for ur prompt advice. I would like to further ask a question on my subject. I understood that the female with whom I am having an affair has been hiding some of her banking transactions with me I asked her about the same but she said that there is nothing as such. . So i took her bank statement of last six months and came to know that she was playing some online games and had almost lost around 10k, So I asked her on this issue. She has got wild on me as to how could I take the bank statement without her knowledge and has stopped talking to me and has blocked my number. I dont think it was a mistake on my part of checking her account as I had a doubt and that proved true. Even then I pleaded to her and accepted that it was my mistake for tracking her account without informing her and also assured that it wont be repeated. But still she is very adamant and not ready to talk to me. So madam how do i convince her and get her back.
