<human>: Could you distill the essence of the text into 1-3 sentences?

Ages: 23M & 21F || Relationship: 3.5 Months
We get along really well, things are lovely. I'm from another country and currently at University. I think this worries him, and is keeping him from getting too 'invested.'  He also is still sort of healing from a break up with his ex of 2.5 years (happened last september) who he still has contact with [they speak on the phone, text, email] 

I spoke to him about his contact with his ex and I told him I trust him, but I'm not sure he knows how much it does scare me. I can understand that he's human and needs time to move on so I don't pester him about her.  I think he's scared to have his heart broken again.  But we'll be talking and he'll suddenly say, "you do know I don't want to move too fast here or anything" and it's a defense, but it kind of hurts me because I feel like a can't trust him and I want to.  We also talked about my being foreign thing, and I told him that my plan is to stay here, because this is where my industry is (which is why I came to university here in the first place)

I'm not running around with fantasies of us being married or lasting forever, and I'm not one of those crazy girls who is trying to entrap a guy.  I'm a take it one day at a time type of gal, and so I treat my relationships as having every potential in the world, I'm not holding back, but I can sort of tell that he is and it's kind of hurting a bit.

How can I share my feelings with him without scaring him off?
<bot>: BF's ex broke his heart, is holding back emotionally in our relationship, saying he 'wants to take it slow' it's starting to hurt me emotionally.
