Search Results: cheating by text message

My girlfriend has introduced me to many of her female friends, and she tells me when she is going out with them.
On the other hand she never talks about her male friends or mention their names, which I find it strange because she has lot of male friends, and they all are kind of her type, poets, writers, film makers, etc.
For example there is this one guy she kept texting 2 days ago while we layed in bed. She was reading this long message of someone called Sean, when she notice me looking she quickly put her phone down like she was hiding something, after a while she was on whats up app, and the name Sean was on top of the list recent texts. I was intrigue so I done a little research on social media i find out the their are firends on facebook, instagram, and that recently she been liking a lot of is posts. She invited me to watch a play written by some friend, I find out using social media that Sean is the friend she mention.
Recently she is spending less time with me, its also been a while since we spend a full weekend together, and all this texing guys that she dosent tell me about, kind of make me thing something shady could be going on. Im not the jealous type, but Im also not a full. I wish I could talk to her about this, but that won't be possible because she usually gets extremely defensive and agressive, everytime I question her secret life. Recently we been having much less sex, and usually says that she's too tired to do it, or she will stop in the middle of it, saying it feels unconfortable. Please guys give me your honest opinion?

i will start of by saying my girlfriend loves me very much and would do anything for me. i am embarrassed to say but i went through my girlfriends phone because of trust issues and saw a text that was off kilter. you can tell the text is more of the guy advancing but it was i knew something was wrong. i told her what i did but didn't really get into detail of what i saw because i was afraid of the truth and i wanted to see if she would come clean. she told me to stop playing games and i admit that i did play a little bit of a game because i wanted her to admit it. I just said "i saw a text'. 2 weeks go by and i finally hit her directly by asking 'who is john (not real name). she played stupid and said i don't know who you are talking about. 2 hours later i sent her an email with his picture. no response and then i asked her again face to face. she admitted it is a guy at work that has been a little too friendly but she told him they are nothing but friends. thats it. she cheated on husband and got a divorce. we started off as best friends and i never thought it would be more. she was asking for more but i was always straight forward with her. things change. i never judged her for her cheating. we all make mistakes. anyway, i mentioned the whole text thing 2 days later. by the way she travels for work which always makes me nervous. now it became i invited him to my hotel room. what? the only reason i think she came clean s because she thought i saw more of the message and didn't want to look like she was holding the truth. regardless, they were drinking after work (me and her were in a fight and i told her i was moving out before she left... mostly out of anger about something i can't even remember) and she went back to her hotel room and texted him the room number. she is a closed person so she keeps things to herself. they were talking about work and then she said she felt lonely and texted her room number. she swears nothing happened and the just talked.
