Someday, someone will leave you. It may be in a good way or bad or even indifferent but they will leave. However, just because someone leaves does not mean that they are forever gone.
Relationships are built on much deeper levels than just that first initial layer. True relationships you have in your life are something that are probably taken for granted every day. Do you know or have that person whom, no matter what, you can't get rid of? They just won't leave, and, to be honest, you don't want them to. But just because they are there always does not mean that you should take advantage of that. Don't get caught up so much in yourself so much and realize that they are people too, and they have things going on too. Rely on that person, but do not treat them badly because one day they may surprise you and leave, and you will have lost the greatest, most real relationship you have every had.
Now if you are the person who always seems to be giving, then I say don't give up. No one deserves to be given up on. The problem is that there are moments when you feel as if it is pointless to still be there for them, but something tells you not to leave, and then the other part of you constantly reminding you of all that bad things you've ever done and why you should not have this person in your life any longer.
With this being said, you still must consider your own happiness and what that looks like for you. Sometimes you need to put yourself first since it seems no one else often does. Don't be afraid to express your thoughts with those around you. At the same time, be aware of the relationships you are in and have with others. If it is swallowing you alive, reevaluate and figure out what's best for you and what you need to do first. If it's just a rough patch, then stay strong and pull through, but you need to be able to recognize the difference and then do something about it.
At the end of the day, it is totally up to you to do what is best for you because you can't love someone if you don't love yourself, but just keep this in mind, whether it is about yourself or someone else.
"Those who need love the most, are the hardest to love."
