This guy creeps hardcore on my girlfriend. Should I..?

[Vincent]

1st off, my girlfriend and I are in a long distance relationship.

This guy has been creeping hardcore on my girlfriend. Ex) liking a lot of her old profile pictures on Facebook, retweeting and favoriting a bunch of old tweets of hers. She has reciprocated by favoriting and retweeting his tweets and liking his profile pictures. Yet, she doesn't even retweet, favorite, or like any of my stuff, or anyone else's for that matter. It's basically only his stuff.

I know this may sound crazy, but we have had some trust issues in the past with other guys she is "friends" with. This guy is single, and in my opinion, clearly is trying to get her attention without directly messaging or contacting her.

However, that's another thing. I don't know if they have been talking via text message, but she does have his number.

While this may seem insecure, and it may well be, and juvenile, it has just made me feel uneasy since we are long distance, have had a few issues regarding other guys, trust, and distance in the past, and this other guy lives back where she is.

I've brought it up before casually, and she said that the entirety of their "relationship" consists of those few things on social media. But before we started dating, she mentioned that she liked him before or something.

What should I do? I want to say something again, but I've already made it clear before that some guys make me feel uncomfortable (unrelenting ex's, etc). What do you think?

I think you're a complete arsehole for not trusting her. She should dump you.

Listen I know what you are going through because at some stage in life all guys go through this. The one thing you have to remember is that trust is a very important thing when it comes to relationships. If you find it hard to trust your partner then something is most definitely wrong because it should never be like that. Your case is special because you are in a long distance relationship with your girlfriend so trusting her might be hard to do. I suggest that you talk to her not about the guy but how it makes you feel when you see him and her interacting on social media. She may either understand and listen with an open mind or she may become defensive and acquise you. Depending on her reaction I think you'll be able to tell where you both stand.
