Believing in Love? Don't! Just believe in your self

I have a reason to not believing in love anymore. I have an adorable 1.5 year old son, and was divorced 3 months ago.
I was living together with my ex-wife since 8 years before we got married, I do love here with my life (this is real), I do everything for her happiness even if it's hurt me, this is why peoples said love is blind :|

Here is my 24 hours routine for my 8 years life with my ex-wife
8 hours = quality time with here, going to theater, shopping, lunch, dinner, etc
13 hours (even more) = working to get money for living, pay the theater ticket, shopping, lunch, dinner, etc
3 hours (even less) = sleeping

I'm a hard worker, because i really need money to pay our living cost, and feed my mom and little brother. In the 8 years she was cheating on me at least 12 times, and almost leave me around 4 times. I was give up at that time, but i still give her a chance.

Then she finally accept to get married with me after i'm waiting for 7 years (i was propose her 1 year after we living together). I think finally i got a happy ending at that time, she got pregnant and we got a lovely little baby boy.

I have a financial problem for last 2 years, which i can't always give what she need like i do previously, even i have to sell my house and car for living. This condition make me working harder to get money and have better life. In January 2016, my wife starting changed, she always go out with her friends, hangout, and going home very late, around 3am, and drunk :|

At that time i think she just bored with routine at home and need some refresh, but this condition getting worst everyday. I have to working and take care of our son which make me can't focused in my job. I'm working at home, just need a PC and internet connection.

In february 2016, my mom coming to my home and talking with my ex-wife while i'm sleeping, she get angry with what my wife doing while i'm working so hard to resolve our financial problem. My ex-wife get mad and act weird everyday, never talking to me anymore even we still living in same house and room.

Finally i decided to asking her what is the problem that make her act like that and doesn't thinking about our family and our son. She answering me with a lot bullshit that not make sense, and finally she reveal the real reason, she said "I don't love you anymore since 7 years ago" whattt??

I'm so mad and can't thinking clearly, her problem can't resolved, after what with i doing to make her happy, it's mean nothing for her, with all love i gave, it's not make her love me, and this is happened since 7 years ago which i didn't notice at all.

So, how i can believe in love if when i felt she love me, but actually she don't? and this happened for 7 years. I'm really give up on her and just thinking about my son future right now. I hope you got better love life than me and keep believe in LOVE!
