One of the hardest things that most of us have a problem with is really listening when someone tells us something. Sometimes, we are fortunate enough when they verbally let us know what they are thinking. Sometimes we have to stuggle with "trying to figure out" what their actions, or lack of actions, mean.
In these cases, the men are not interested in long term. They are telling you. Why don't you listen??
Rejection, abandonment, issues of being alone or old and having no children, these are all valid concerns. But on the flip side of this, look at your lives 5-10-20 years from now with a man that never really loved you or never was really able to commit to you, might possibly work too much, cheat, get into porn and strip clubs, hang out with the guys all the time, leave you alone and lonely........then rewind to this moment in time and rethink how YOU can make this work for YOU if you YOU want to!
So many times I hear women blame men for their inability to commit, when they knew way early (women's intuition is key) thats why we got it ladies......that their men were, uh, not really into us....but enough that we would settle because maybe one wants a baby, or a nice house, or prestige in the community, or guaranteed sex every nite....:))) but this is not the way life is. It is sometimes, and its not, sometimes.
The worse thing we can do is ignore what someone else is letting us in on, and ignore what our intuition is letting us know what is happening. Its not uncommon to find it easy to believe a narcissistic person that tells you what they know is going to get to you, but then the narcissist doesn't want to associate with anyone that would have him as a member.......woody allen 's quote. lol
Be thankful that he is letting you know he wants to travel alone, or doesn't know what he wants, because if you manipulate him to stay, and then get a loser or someone that is a sheep, you will forever be on this board wondering "what/why/how" did life get so complicated.! Take it from someone who has been there, being alone might have its down sides, but choosing to ignore what is right in front of you, is just being plain stupid and following your fears.
