lack of proper communication, quality time together, too pushy, conflict-avoidant... 

Expect you to have intimacy with them after been dating only for few weeks and fake their emotions just to impress you... eughh.. T_T

I think that its the lack of time you get for your friends and yourself, you have to learn to split your time for everyone, that one is the hardest for me 

still being in love with your ex even after three years of your breakup :)

that you often forget about yourself. you often put your needs down in order to keep your s/o satisfied- and also lack of free time

Lo peor es cuando ambos lados quieren estar juntos sabiendo q no se soportan,es decir,pelean y se maldicen seguido pero no sé alejan por el echo de que se aman,es lo más complicado porque nadie quiere terminar esa relación,es jodidamente cansado,no es fácil lidiar con eso 

SOBRE PENSAR

La mayor parte del tiempo nada está pasando realmente, pero la idea de que algo podría ir mal o ver cómo otros van mal y yo no me he dado cuenta pone en duda mi relación, mi juicio y mi autoimagen 

My ex actively hated what I enjoyed in my free time. She wouldn't stop being an ass and complaining about how she didn't like it, even though she wasn't there. (she was texting me, or on the phone)

She only wanted to be in bed. That's not what I wanted. Don't get me wrong, I loved doing it every so often, but that's all she wanted. 

I love sharing music with people I care about, but she never listened to any of it. Ever. She hated anime, saying that it's 'too flat' (which I can understand), but she watched Big Mouth directly after saying that.

Broke up with her after about a year and a half. 

Highschool romance sucks. If you're going to get a gf (or bf), make sure they have similar interests or personality.

constantly putting them above you, even in a perfectly healthy relationship it can be hard to remember you can have your own opinions/likes/etc without it having to please them!!

that the person is too jealous

The worst part is probably the breakup itself, giving things back to the other person and coming to terms with the fact that they are no longer your partner

PAGPara mi seria las inseguridades, si van a andar de novios, por favor, eaten segurisisisimos de k la Otra persona los ama, es feo sentir inseguridad en ese sentido y mas si eres una persona con apego ansioso (T^T)

Well, that probably depends.

One-sided relationships suck

Dishonest partners suck

Abusive partners suck (mentally and/or physically)

Situationships suck

Ect.

I think something that sucked for me in a relationship I had around a year ago was an age gap of 5-6 years (I was the younger one). The woman I was with broke up with me because I was too young, even tho we were on the exact same level and we have fit perfectly. Sure, she did the right thing to break up with me (even tho it is legal in germany in some way) but it still hurts to know that the perfect relationship didn't work because I was just too young.

Only my thoughts on it tho!!

not knowing if he's flirting with others or just being friendly..
