Hello there! :) As I ব্যক্ত in the title, this is moslty directed towards boys. I've just witnessed a lot of আপনি being intolerable jerks, (not all of you, just most of the guys where I live) and I'd like to share my knowledge. SO JUST STOP RIGHT THERE and let Hazel give আপনি some advice. :)

1. When আপনি introduce her to your friends, introduce her AS YOUR GIRLFRIEND.
Don't just say- "Oh, this is Penelope. Anyway..." Nonono, rather- "Hey guys, this is my girlfriend, Penelope. I প্রণয় her, so be nice." When আপনি introduce her to your friends, it shows her that she will probably be around for a while, which makes her feel special.

2. (If at school) communicate with her silently from across the room.
Whether it's just a smile, wink, অথবা anything of those sorts, it will brighten her day. Seeing the boy she oves smiling warmly at her will make her tummy tingle.

3. BE HER BEST FRIEND.
This is extremely important, hence the capital letters. When আপনি are in a relationship, being প্রেমী seems amazing, right? The warm feeling আপনি always get when আপনি two kiss, hug, share intimate moments, ect. But after a while, if all আপনি two are is lovers, it begins to get old, অথবা boring. There ARE times in relationships when আপনি randomly don't প্রণয় your partner as much as আপনি normally do. During those times, if আপনি have a friendship with your partner, আপনি will have something left. Ever seen couples who are married at a very old age when they are all wrinkly and saggy and a bit gross? They had that best friendship. If আপনি are JUST lovers, আপনি won't want to be প্রেমী when you're all saggy.
Does this make sense? Laugh with her. Share inside jokes with her. Play games with her. Go out for coffee and just talk about your day. A best friendship for me is looking at someone from across the room and being able to have silent conversations with just facial expressions. She will প্রণয় being your best friend.

4. Have "a song" অথবা "a food" অথবা "a show".
This also goes with being best friends. There is this boy that I used to like- Our Song was "If আপনি Wanted A Song Written About You, All আপনি Had To Do Was Ask" দ্বারা Mayday Parade. (We weren't dating, but আপনি get the point.) If আপনি two had a প্রদর্শনী and it was... "The Office" for example, every time a new episode came on, আপনি two will make some popcorn, scurry to the TV, and snuggle up & watch, happy as can be. All the while, আপনি are eating... String cheese, which is "your food". Are আপনি getting the point?

5. Make her feel safe, but let her make her own choices.
Girls প্রণয় the feeling of being নিরাপদ in their boy's arms, being kissed on the forehead, just being protected. But আপনি can't be TOO protective, because she'll feel restrained and powerless. Example- if some guy is flirting with your girl, kick his ass! But don't make her stop talking to her guy friends. It is a bit frustrating when the boyfriend is overly protective.

6. Be sweet to her, but আপনি must also be firm.
This reminds me of a South Park episode- Satan loved Saddam Hussein AND this guy named Chris. He loved how Chris was sweet to him, but he was just TOO sweet. Satan hated how Saddam was an asshole, but Saddam was was also firm and it was attractive to Satan.
(Translation) xD
Be very sweet and nice to your girlfriend. She should be a princess to you. But at the same time, if she lies to আপনি অথবা does something that upsets you, (flirts with another guy, cheats, stays out too late) আপনি have to be firm and scold her. Set boundries. Every girl wants a sweet guy, but if আপনি don't set boundries, she may feel free to continue to do some bad things. Don't be so firm that she is scared of you, just enough that she understands that আপনি care and আপনি are worried.

That's it for now. :) I'll make another one later! <3 See আপনি all.
