So these things happened all over the course of a few months. My ex boyfriend (we'll call him E) has a friend, well call him X. They haven't been friends for very long, but I want to say I'm not trying to DO anything with X.
One of the first times we hung out as a group X hugged me and asked me what perfume I was wearing, and said he'd buy it for a girl he'd potentially like. he's told me I look cute more than once. Every time he sees me he ends up standing or sitting close to me. E even pointed it out once. He hugs me everytime he sees me, but he hugs everyone. X has laid his head down on my lap a few times, when I was laying on my friends bed X would lean on my legs to prop himself up. I laid on his lap once back but it resulted in a accidental nip slip. He touches me a lot, like brushing my arm or hand, and resting on my legs, getting thing out of my hair, once I had something on my inner thigh and he brushed it off. He bought me drinks for my bday a while back, I remember that night he was tipsy and gave me a long hug. He asked for my number multiple times. X would tease me scrolling my phone to make me lose my place, or bothering me until I say the magic word. He's called me "good weird" before. Also sometimes in a group he'll end up just talking to me. E has said that he thinks X is into me because he always asks about me. E has said this exactly "if I were insecure the things he does with you would upset me". E has said once before that X treats me differently than other girls he's seen him around. X always talks about other girls he's into. And on social media he's shown me girls he likes, but they do resemble me a lot. I'm not sure if that's on purpose. X recently got a new girlfriend, I haven't met her but she lives like 2 hours away. I saw X like 2 days ago and even though he has a girlfriend now he still did all those things. Like touching/laying on me, getting things out of my hair and he randomly started taking pictures of me.

In the initial stages of getting to know them, you remembered when their birthday was because you asked. But it was told about two years ago.

You both reconnected after those two years and it seems they like/missed you even more from when you were absent. You're more acquainted with each other and are always greeting each other. They are trying to be more open with you now, but still acquainted. They are friendly and nice towards you, talk to you more when it's just you two alone, and show subtle signs of liking you but isn't entirely sure how you feel about them.

So even if this is the case, is it too much to get your crush a simple gift? Like a tumbler/thermos for their birthday?
