Don't want to be hurt..

So on Monday, I delivered the guy I'm talking to now some sweets for his sweet tooth randomly. We've been texting less and talking less as well but we're still texting everyday. I see him mostly on the weekends when we hang out with our group because he's usually off on Fridays and Saturdays. Lately he's been making me feel like he's not interested or doesn't want to keep this up. Then again, he still talks to me and still stay on the line with me when I fall asleep. I'm not sure what's going with us. I'm not sure if he wants anything to go on. I recently found out that he's been through some rough times with his ex and girls he used to talk to. Maybe that's why he's not very expressive. His brother's girlfriend told me that they were surprised of how much he talks/texts me. They said the only girls he talks to are those who have boyfriends or people he sees as sisters. He don't even talk to them as much as he does to me. Another thing is, they've noticed how quiet and shy he acts whenever I'm there with their group. He usually talks a lot but when I'm there he barely says anything. We always have these awkward eye connections and just look away. I'm afraid to be hurt again. Should I stop talking to him? I feel like he's on and off. Somedays he makes me feel like he wants to talk to me and other days he makes me feel unwanted. I don't know if I can keep this up any longer. I don't want to be hurt. I'm tired of being hurt. I don't want to seem like I'm all over him if he's not responding back to me. Maybe I'll just back off for a bit.

As for the guy in Vietnam, I've already told him how I feel. He completely understands and we're still good friends. Honestly, I'm getting sick of talking to guys. I'm sick of always putting in work when they just seem to brush me off. This time I won't let myself fall into something I know I won't get out of. I feel triple cautious now. I guess that's what becomes of you when you've been hurt one too many times. If only guys could understand more and be more considerate.
