I had noticed some distance from him since he game me the ring, bad enough that we have a long distance relationship, well after a huge argument about him and what I have been noticing he asked me for time off on the engagement! And he have no reason, I think his scared of commitment and that just kills me his 35 and I'm 31 and we both have children from previous relationships his never been married but I have the whole works church and everything, I'm just a rollercoaster of emotions. I feel betrayed, used, I LOVE him with all my heart but I just don't understand how can you do this to the person that you say you love! Know were still dating but he acts like if nothing happen.:(

Do I give him the time he needs or should I just move on??

Both. He asked for time so you have to move on. In the future you can re-evaluate the relationship should he change his mind, but at this point you should presume he's not going to.
