I am to getting married to a man I have been in a long distance relationship with, but his coworker has been a huge redflag so I am no longer sure about getting married to him anymore because of her.

We have been in a 3 years long distance relationship, but finally we decided to get married last month. The problem is that we have been planning to get married for about 6 months but I think we rushed into it too early. We decided to get married because I got pregnant, I am almost 2 months pregnant now. The problem is that we have not spent much time together because we are from different cities, only 2 months and a half together, and I can’t spend more time with him because I am already 2 months pregnant. Originally we were going to have a long engagement, we wanted to spend time together and get to know each other better, but my pregnancy rush us into getting married quickly, only 3 months.<br><br>&#x200B;<br><br>We had our civil wedding last month, and I have to move in with him at the end of the year. The problem is that I have been getting some redflags from a coworker. It has been some time since I have been doubting if I am doing the right thing. We had an argument over this issue and he told me that I should not trust his coworkers more than his words. I should be able to trust him, and it is disrespecting to question him over this.<br><br>&#x200B;<br><br>I have met my fiancé twice in person. We had sex the first time we met in person, and we had sex for the very first time in a hotel room. We had sex almost all day long, all morning until the afternoon. We had sex like 5 times until he came back to his city. The problem is that his coworker told me that he had sex with her like 5 times in a day as well. She told me that he invited her to his house and they had sex. She said that he has a huge libido and he is a very “energetic” man. I am not sure if I should believe her or not. She told me that they had sex some month ago, so before he proposed. She said that they had sex because she was very sad over a fight she had with her boyfriend, so he invited her to his house and they had sex. But the thing is that he told me that he invited to his house to study because she was having trouble in his psychology class. He told me that he helped her to study and she was really grateful, that is why she bought him a gift (a watch) some time ago. But it seems like she was not only studying when she was over his house. <br><br>She also told me that he has been very frugal the whole relationship, while his coworkers and friends have had some luxuries like designer’s goods because he earns a good salary. I don’t know if I believe her or not, but at the same time I am having a hard time to believe him. I don’t know what to do anymore. <br><br>&#x200B;<br><br>I am not sure if he is cheating or not. She has been sending him messages everyday, asking him to get drinks. She told me that they had a conversation over text messages everyday while he told me that they had a conversation once a week over text messages. She also told me that they went to the bar together and he came to her house. He told me that he went to the bar with some colleagues and she was there and only had a conversation with him. She also told me that she had a huge crush on him and she sent him a sexting message while he told me that she only asked him for some relationship’s advice. She also told me that he told her that I am not very attractive and he only sees me as a mother of his child.<br><br>&#x200B;<br><br>I sent a screenshot of her message to him. The message is very weird and creepy so I am sure that he would call her out for sending him a message like this. But instead he did not say anything about. She told me that he did not said anything about it. I told him that if she keeps doing this, I will go to her boyfriend and tell him that she has been flirting with my fiancé. He told me to drop it and he will handle it. He told me to not talk to her boyfriend about it. He wants to handle it by himself. The thing is that he has been handling it for a while and she still keeps texting him. He told me that he does not want to ruin their working relationship so he can’t be too harsh with her over text messages. He told me that he will talk to her in person once they are back to the office.<br><br>&#x200B;<br><br>I don’t know what to do. I am really confused. I don’t know if I should doubt him and his coworkers or not. He was the one who wanted to get married so bad, so I don’t want to think that he is cheating on me while I am pregnant. He told me once that he wanted to get married to me no matter what, and now I am doubting him. <br><br>&#x200B;<br><br>I don’t know what to do. What would you do if you were in my shoes? Should I doubt them or not? I don’t want to think that he is cheating on me.
