When we are together he is really sweet and seems into me, I have seen his friends, we have texted, he called me, we have had sex (5 times on the 3rd date), he texts me after to make sure i got home safe saying it was good to see me, texting hearts and liking my pictures, he asked me out. Then he doesn’t text again, then he says next weekend, I asked him yesterday and he hasn’t replied yet about this Friday. What is this? Why is he doing the hot and cold, not even reading the text when one day before this he commented a heart on my picture. I am 23 and he is 27, from we started dating it sounded like he was looking for a serious relationship.
