Been on a date twice with this guy, we both had a really good time etc been talking on phone and messaging through day and night and know he has just told me that he's been talking to his ex and gonna give it another try with here! Many advice will be grate...
Well, as you've stated, he wants to give it another go with his ex. Keep in mind it's not you. You didn't do anything wrong. Something in his last relationship was not finalized. That is clearly between him and her. She could've done something stupid and begged for him to come back, sometimes you miss people when you aren't around them, or something else. At least he told you, right? He isn't leading you on, so that's a bonus. My only concern is if he and her breakup again and he wants to talk to you again. Just be careful. You're not a backup plan. If that situation arises, be upfront and tell him how you feel.
There could be hundreds of reasons, or it could be he is just lazy, I say this with the expression in mind that "the devil you know is better than the one you don't" and no I'm no saying your a devil, just that he already has a basis for that relationship, and while he may not have gotten everything right, the things he did get right are now known, thus those are things he doesn't have to learn with you, which is where the lazy part for him comes in. Relationships take work for both parties, and it sounds to me like he isn't willing to work on something new and possibly better. You should feel encouraged that you are not going to have to try and live up or perhaps down to what he had become accustomed to with his ex.
The devil you know: Maybe he was with her for too long and began to suspect she was crazy, so he went on a date with you and you reminded him that all women are annoying and insane so he decided to go back with numero uno; plus she heard he went on a date and is now pulling out all the stops to get him back because nothing turns a woman on like another woman wanting a man.
why do girls stick with guys that give them hard times? why can't you just find another guy completely, i mean come on, your a girl and you can have just about any guy you want, guys are not that difficult to get, were not like girls and impossible.
It's nuce that he is open and honest about his situation. Now that you know. You have to decide if you want to take part. You should also date/talk to other people till you meet one who you both want to be in a committed relationship.
