Met a guy this halloween because I am friends with his brother. We eventually have been talking everyday for a month now. We went on 3 dates and he kissed me on the 4th. He seems really shy sometimes but I may be wrong.

The main problem here is that he always hints at doing stuff with me, but never actually says "hey let's do this today".. he hints, and I have to be the one to ask him if he wants to come over and he always does.

One thing that mainly bothers me is that he takes forever to texts back. I'm talking like 1-3 hours. It frustrates me because we can never make plans because he takes so long to respond and the day just flies by. I have joked around with him about it before and he just laughs. He's not into technology or his phone a lot (says his brother). But whenever his phone rings when he is with me, he does check it. When he does respond, they are long texts and showing interest in me, so it confuses me. There have been times when he checks my stories on snapchat, but hasn't responded to my texts.

Why does he take so long to respond and doesn't initiate hanging out plans? He hasn't had a gf in like 4 years bc he is always busy with school but he has a lot of free time on his hands. I went out yesterday and he said "you should've invited me bc I just stayed home".. I'm so confused.. Help :/?

I met this guy on Tinder ( i know, bad idea). and we met up once and i thought he was pretty cute, but never made a move and he texted me like a week after asking if he had scared me away. Long story short, we ended up meeting again and ended up making out at his place and he asked me to spend the night. I didnt have sex with him but I did sleep there for a couple hours. I left early in the morning and he kept saying stuff like "next time, bring this", or you should come back for more amazing kisses". Anyway, he s not one to text, so he hasnt reached out to me, but i didnt text him either. I know for a fact he s single..

Whats his deal? , he s 24, im 22. If it even matters.

Met this guy about a month ago, he seemed really nice, polite, and genuinely interested in me. On a night out, he met my sisters and talked to them and and my brother in law all night. Later that night he said he liked me so he wanted to get to know the rest of my family.

We texted all day everyday for almost a month, but when we saw each other more, the texting got slower and less consistent. He kissed me about twice and then invited me to an event from his work. I didn't know anyone there so I was quiet at times. I invited him over to eat that night for the next day and he gave me a lame excuse for the 3rd time so that kinda threw me off and the ride home was awkward.

He asked me what I was doing the next day since he was gonna be on this side of town too. Didnt kiss him or anything and he semi-walked me to the door. I texted him that night if he got home ok and he said "I did! thanks!" I replied Ok good! and the next day i texted "goodmorning" since he always texted me first..I told him i was sorry about being quiet in the car but that it had nothing to do with him.

He completely ignored that and talked about something else, only to ignore my text from then on while he was active on social media. Haven't talked since that day and that was 2 days ago. Then he liked one of my pictures on fb which was weird...

Did i do something wrong? I never pressured him into a relationship or even talked about the future.

ive been talking to this guy for 2 weeks now and have gone on one day, didnt kiss him and it went great, texted me after and we talked/ flirted normally.. He has an instagram and an ex gf who uploaded a pic of him as a man crush monday, just thanking him for always being there and stuff. And yesterday night he uploaded a "woman crush wednesday" with her pic, thanking her for being there when his mom got sick and when bad things happened to his family. But he keeps talking to me normally... Should I be worried? He even asked me out on a second date :/

What effect would a screen have in the clarity of an image?, how about looking through the pin hole?
