You need to get to know someone well enough to make sure you're not making a mistake. You also need to talk to the person about your relationship as a whole.
As long as you feel you can stay. If you have the patience
Then he's not the right guy.... for you..~
Hopefully not very long because if it is a bad relationship someone should break it off; nobody should have to be miserable if they can do something about it.
A few months.
It can last a long time if you are both committed. I have been in a long distance relationship for 7 months
If your friend told you that the guy you like is in a long distance relationship you should probably look for someone else. Long distance relationships are difficult enough to manage without obstacles.
You can say that you're in a committed relationship, or a serious relationship, or a long-term relationship.
You ask him. Long distant relationships are all about trust. If he does admit he has feeling for someone else, you two can talk about it. If not, you'll know. If you don't think you can trust him on the phone or on the net, you should get out of the long distant relationship, one way or another. That's my opinion
you should get back together with the month long relationship and tell the other guy I'm sorry but i have feelings for a different guy
A long term relationship can be defined many ways, just depending on the person defining it. I feel that a long term relationship is several years long, however someone who is single may see 1 year as a long term relationship.
It's not that they are afraid of a long distance relationship. They know they don't have the feelings for you that they need to have in a committed relationship, but they don't want to come across as hurtful by being honest about it. The best thing you can do for yourself is realize that the feelings needed for a genuine relationship with this person (long distance or not) are simply not present on their part. Don't focus anger on them or worry that you are lacking in some quality--attraction is often an uneven thing, sometimes people like you that you just don't feel a spark with. Just realize that you deserve to be with someone who doesn't have to debate with themselves about being a part of your life.
A successful relationship is not defined by age, as long as it is not breaking the law and as long as each partner is committed then there is no reason for it not to work.
Just follow your heart and don't let anything get in the way. If you live someone you should stick by them but if it's a long distance relationship you'll still see each other. Hope that helps!
