Does this seem a plausible reason to be jealous of a spouse/girlfriend?

Question

Well, I hate to bring my problems online and ask people who don't actually know me but I've been seeing and noticing things my girlfriend has done and is doing that really gets me to thinking she might be unfaithful. The things I have found are: 1: She has left several "suggestive" comments on two her friends MySpace accounts, one of which is an ex boyfriend, and one of which who used to like her. The comment to her ex was "is that a promise" to a picture that said "I'll be your desire" and the one to the other guy was "don't tell my boyfriend this but you pretty freaking sexy".
2: She will not answer her cell phone unless its one of her female friends, and occasionally lies on who is calling.
3: She won't allow me to see past messages on her cell phone /myspace because thats "How she is"
4: She has ended phone calls with me at night to talk to other guys.

Does this seem like a good reason to be supsicious? Or am I just an overjealous boyfriend? I need help...Thanks

We were also dating while all of these has happened, and I don't feel right being suspicous if I'm just being overjealous, and I need help.

Answer 1

that's the whole reason why we date - there are way too many hot women who will be exclusive to you at any given time. Take this time to make your happiness predominant in a relationship - if it's not met - do not go looking at her behavior but you change yours, dude. Move on the time is right

Answer 2

it is very obvious that she is up to no good. honest people have nothing to hide and wouldn't hesitate to show proof. tell her to stop hiding things or you will start looking for an honest woman.

Answer 3

AND SHE'S STILL YOUR GIRLFRIEND?????

SHE'S USIN U LIKE A DOOR MAT DUDE..

Answer 4

sure is move on
