if you guys are talking all of a sudden again, theres a reason. you guys both still like each other but dont wanna admit it for the sake of keeping things pure and easy for now. but its right in your faces
if you feel like doing any of that stuff, just do it. its in your instincts, and you should learn to trust those a bit. but consider that the pre-getting back together phase will almost always feel blissful like how things are before the break ups. you gotta learn how to carry on that feeling and satisfaction through out the relationship so you wont need big break ups to feel like youre missing something, ya feels? its deff hard tho. I feel its humanly impossible to appreciate something or someone 24/7, but that doesnt mean drop things soon as theres nothing left to acknowledge. remember, she has feelings just like you do.
this is all advice from experience, so if Im mentioning anything that seems out of context or useless, just remember, it happens to the best of us.
anyway, so instinct. you guys are talking to each other out of the blue cause you obv still care. now our human side will always balance these situations out if you tend to break up a bit. but no matter how much evaluating we try to do, deep down we know what we really want. so you asking if its too soon is only contradicting what you really want to do, which is something for her bday/valentines. you brought it up, thought about it, made a conscious decision that took time out of your membrane. face it, you want to.
and once yall do get back together, thats all on you. theres not much advice we can do, cause 6 billion people in the world, and each give their own special combination in a relationship. but if you guys are as close and tight as you say you are, just be positive and find out what your strengths are that kept you two together.
ps, youre taking advice from a newly turned 20 year old, so fuck do I really know?
