how long can i continue like this?

I suggest you to think about it again. for me 3 years was really an enough time to trust your partner and never thinks he/she would have cheated on you while you were away. thinking about how he thinks of you i guess he haven't trusted you yet and doesn't have any faith on you. he sounds not to know you better either. my boyfriend and i were been together for 5 long years. and after some time we find this kind of issues as jokes. we even tease each other having crushes. but we never had serious talks on cheating coz we know in ourselves it would never have happen. although maybe our situation's a bit different coz you're in a long distance relationship, i guess it should not change the way you feel about each other.

I think its irony. the guy suffers from something which can't be mended. he is very insecure by nature it seems. so whatever may be the case, he can't trust the GF. In any relation, trust is mos important thing.

Hi,I think he love her very very much,he cares about her,even her whereabouts,maybe they have to keep post with each other constantly,and let him know how much she loves him.

I don't know about someone being so controlling and suspicious all the time. You may want to reevaluate your relationship and talk it over with the guy.

I will send a message for this type:

"If you want to seek a woman who can do just like what you want, maybe I'm not the one."

He will call shortly after received this.

Yup i agree with you, quiet a reasonable advice, she should consider her relationship . He is like overly possesive, that man has no trust or respect for her. And if she continues, its like she has to live with all of that the rest of her life....

Has she considered ever talking to him about his insecurities revolving around the stability of the relationship?

There is a reason as to why he has suddenly become like this - has she been thoroughly honest with you when asking for your advice? Men who have been trusting of their partners don't suddenly become suspicious for no apparent reason.

I was part of a long distance relationship (LDR) for nearly four years with my husband and I find that talking, keeping in touch and being honest about EVERYTHING helps a lot. Trust is very important in an LDR.

If they can't patch things up, then one option is for her to break it off. Yes, she is still young but if they are in love and are serious in moving ahead, she should find out why he feels the way he does before calling things off.

An insecure person who will not allow you talk to someone or is suspicious of who you are with or where you are IMO is like an abuser and unless they get professional help they are UNLIKELY to change. I would cut loose now while he is in another country and move someplace else so if or when he comeshome you are not there.

In my past experiences with my friends, Their ex BF's were doing or acting like that only to find out that they are the one cheating. They are the one who are doing doing things and for doing so, they tend to think also that their GF;s are doing the same! If that will continue, it is not a healthy relationship anymore, happiness will never be in with them. Instead, they will always end up arguing things because of false beliefs or non sense issues. It is better I guess for the girl to move on and look for anyone who is mature enough to handle relationship! Maybe by doing so, her Bf will realize that trust is the basic foundation of any relationship plus love!

Sounds lke you told her pretty much what I would have. If this is guy who works away a lot, they will be facing this suspicion constantly. If he doesn't trust her, then he doesn't know her well. I agree with you that she should rethink it.
