Being in a relationship means that you both try and make the relationship work. You care for each other. Loving your boyfriend isn't wrong, but when he becomes a literal baby to you, and you always have to clean up after him. Girl, you're caring for him, not dating him.
Here are some factors to determine if your boyfriend is your child instead:
If your boyfriend gets upset by stuff like cleaning his room or going to work, he's not mature enough for you. The easy life has taught him that those are your responsibilities. His task is to sit back and wait for everything to be done.
Ideally, it's a man's job to ensure that his girlfriend or partner is comfortable financially. If it's the other way round, it should be enough to arouse your doubts. Lending him money once in a while is alright, but if you're the only one giving the cash, it's time to open your eyes and see things as they are.
Most men find it difficult to keep their stuff and probably themselves in order. Don't judge yours for that. There's no problem in organizing his stuff and cleaning up for him, but you should rarely do it. He's a grown man. His stuff is his responsibility.
If you're always comforting yourself saying that he'll change and you keep making excuses for him, it's time you do yourself a favor and dump him. You deserve so much better than wasting your hopes on him. No matter how many times he knocks, don't let him into your life again.
Procrastination is totally fine, but if it's overdone, that's a whole other story. If your boyfriend hesitates to carry out tasks that you ask him to do and keeps putting them off for later, he's clearly showing you that he doesn't care about your feelings. He wants you to get the tasks done for him.
Arguments are a normal part of every relationship. You shouldn't worry if you have one with your boyfriend. Your main source of worry should be when he insults you during the arguments. No matter how pissed off he is, he should have self-control. Don't keep forgiving him. Leave him.
If your boyfriend is unemployed, him looking for a job doesn't matter. What matters is how he reacts if he doesn't get them. If he keeps talking trash about them, he isn't mature enough to handle disappointment like a man.
Both people in a relationship are responsible for its growth. If you're the only one with the plans, you call him, buy him gifts and take him out, please stop. You aren't the only one in the relationship. He should contribute as well.
