The body's natural stimulant, adrenaline increases your breathing rate, and causes your pupils to dilate. It also causes the blood vessels deep in your muscles to dilate, in order to get more oxygen and more energy where it's needed most. The veins in your face also dilate.
Intense feelings like stress, anger, or embarrassment can cause the blood vessels in your face to widen. This is a normal reaction of your nervous system but can be severe if you have anxiety. If your emotions make you feel flushed, you could also notice: Sweating.
Since he's blushing it means that he's nervous when around/talking to you. If a guy has no interest in you, or doesn't like you more than a friend, why in the world would he blush when he's around you? But, keep talking to him and get to know him better, just don't rush things too quickly even if he does like you.
Given the right stimulus (such as embarrassment), the nerves prompt the blood vessels to open wide, flooding the skin with blood and causing reddening of the face. In some people, the ears, neck and chest also blush.
A guy might blush around a girl if he has romantic feelings for her or finds her attractive. But why? The emotional response you have to being around the person you like causes your body to release adrenaline, which makes your veins dilate, bringing blood closer to the surface.
Blushing is the reddening of a person's face due to psychological reasons. It is normally involuntary and triggered by emotional stress associated with passion, embarrassment, shyness, fear, anger, or romantic stimulation.

Blushing is one of the subtle signs he is secretly attracted to you. When a guy is attracted to a girl, his heart rate increases when talking to her, his blood pressure rises, and he will blush. If you notice him blushing whenever you are talking to him, it is a strong indication he fancies you.
If you notice him leaning in towards you while you speak, he most likely is interested in you romantically. Pay attention to how often he leans into you. If it's almost always, it's a good sign of him liking you.
If you notice that a guy blushes around you, this is one of the most obvious signs he is trying to flirt with you.

When we are attracted to someone, blood will flow to our face, causing our cheeks to get red. This happens to mimic the orgasm effect where we get flushed. It is an evolutionary way the body tries to attract the opposite sex. This is why women wear blush.
Although changes in blood flow may precede conscious emotions, blushing in humans strongly correlates with emotional arousal.
People of all skin tones blush, but it may be harder to notice in those with darker skin. Women reportedly blush more than men, but the one study that measured gender differences did not find strong evidence of this.
Blushing
Blushing, especially facial blushing, is a big nervousness body language cue. It is also something that is much harder to control than many of the other signs discussed above. It is a natural reaction of the body and is not necessarily something we can turn on and off.
When we're embarrassed, our body releases adrenaline, which causes our blood vessels to dilate, in a bid to improve blood-flow and oxygen delivery. And, blood vessels in our cheeks are wider and closer to the surface, than other parts of the body — creating the reddened appearance.
Physical, emotional, and mental abuse are undeniable red flags in any relationship. Physical abuse is easier to pick up. But emotional and mental abuse can be just as damaging in the long run. And just like physical abuse, mental and emotional abuse can cause PTSD.
