My gf lied about something in her past.

It bothers me that you talk about looking at her texts and monitoring her interactions with guys. That's not something that belongs in a healthy relationship, and totally aside from who's slept with whom, it could be a bad sign for how much trust there is in your relationship. It isn't fair to dictate to her who she can talk to or follow. She's your girlfriend, not your pet; you can't leash her.

She was embarrassed by this incident, not turned on by it or interested in repeating it, so why does it matter so much to you? You've only been with her for five months; there is still a lot about her you don't know, and vice-versa.

Lighten up. If you can't lighten up and let her be with you by choice instead of by your constant vigilance and snarling at other men to keep them away from your "property," then do her a favor and break up with her. Jealous, controlling boyfriends are awful.

How old are you? I think that a partner has the right to keep things for himself/herself and not share it if he/she feels that it's not the right time and if he/she doesn't know if the relationship will become serious or not.

Your curiosity is killing you. You have certainly asked her many questions and now that you have the answers it is bothering you.

you need to apply the mental leash on that hoe

Straight up , you fucked up , you hit the idiot gear take it as a loss and learn from it , yeah your a lil bitch for caring about
People she slept with, but your right to be jealous , I feel you dog ,trust makes relationships but it's doesn't help them grow it just makes them stable , she lied to you , now your paranoid but you truly need to get over it , most likely you never will get over it , but guess what no one can . The people that are telling you to grow up and are mad at your for asking are the people on the other side of the relationship , your girls not a slut she's just a person , although Judging someone based on there past isn't okay , it's truly what makes you yourself , everyone likes to act like they get over shit , but they don't they just forget , don't kid yourself jealousy isn't okay but it does bring a clear picture of you and your partner

The BIG PICTURE here,, We ALL have a past when we find ourself in a relationship. Her past is her past, Your past is your past. Drop it before she decides to pack her stuff and move on to someone that isnt so hung up on THE PAST, as in YEARS BEFORE SHE MET YOU. Maybe she was embarrassed, or just didnt feel good about the decisions she made in her life. You need to let it go before she rethinks the decision to continue dating you. But also,, I will just bet you are the Jealous sort of guy. Jealousy is like cancer,, it will tear lives apart in no time.

It's none of your business who she slept with before you met her and you sound insecure by asking her and making her feel she has to prove she isn't talking to other guys.

If you keep that shit up she will most likely leave you and I wouldn't consider 5 months a serious relationship. You're still in the honeymoon phase..

Okay. I consider myself to be a guy with minor trust issues, but you are going a little over the top. It's okay to be worried/overprotective of your woman, but you can't obsess over these things. If you are worried, talk to her. Communication is everything. I recently got a little jelly cause my gf told me her ex said certain things to her that made me want to kill the kid. We talked about it calmly, got over it. If you can't talk about it, your relationship may be in trouble. Best of luck

Did you find out why it embarrassed her? If she didn't want to admit it to herself, telling another can be quite dfficult.
