Women tend to decode a man's love based on how a woman feels, but most men think differently. Men use their sweet and loving words to keep women close, but these casual displays of affection usually do not validate any deeper feelings in them unless you also see a few very undeniable signs he's in love with you.

Biologically and socially, men are set up to seek, express, and be rewarded by love in different ways. A Cognitive Therapy and Research study looked at the contribution of genes and culture to the expression of modern romantic love and found that love "is characterized by a range of cognitive, emotional, behavioral, social, genetic, neural, and endocrine activity [and] occurs across the lifespan of men and women."

You'll know a man's in love when he starts doing these sweet things, according to psychology:

1. He's consistent

A man who is seriously interested in being in your life forever will make sure he's in constant communication with you. He will text and call, no matter how busy he gets. He makes a point of being consistent by showing up and keeping promises.

Moreover, he will plan to see you every possible chance he can. You won't ever have to wonder why he isn't calling, texting, or why he's not taking you out on a date. Because he will be very forthcoming with you.   

He invests his time, money, and affection without fail because he's deeply in love with you and is in the presence of the woman he cherishes.

3. He's vulnerable with you

When a man is deeply in love with you, he opens up emotionally. He communicates his deepest feelings with you, his playful side, and, yes, even his flaws.

Men are afraid to be vulnerable because it can be incredibly painful for them to be seen as "weak." However, he's ready to let his guard down for the woman he loves because he wants her acceptance.

When a man becomes vulnerable, it's usually a sign that you're welcome in his life. He wants to connect with you on a deeper level, and he's doing so by letting you see a new side of him. For many men, emotional openness and coordinating their emotions with a partner are dependent on cooperation. A study from the Journal of Social and Personal Relationships found "men showed the most positive emotional experience at high levels of cooperation."

Whether it's his parents, his grandmother, or the friends he's known since he was a child, he doesn't hesitate to introduce you to them. He's excited for them to welcome you into their lives. A series of studies investigating social effects on romantic relationships showed, "relationship approval from family and friends leads individuals to feel more love, more committed, and more positive about a partner."

6. He believes in you
