Is she into me

So I’m a guy here. And I’m bad with reading signals. And I can’t tell if this girl is into me.

So we’ve been texting/calling/Skyping for about a month now. She always laughs at my jokes (which aren’t that good imo). She texts me smiley faces, she’s asked me to skype a couple times.

She’s showed me photos of her, and we get along really well. There’s just this worry that she just wants to be friends in my mind. She did mention once about a guy who hit on her when she thought they were just friends.

Should I just ask? I don’t want to ruin our friendship but at the same time I feel there’s more.
