The Desperate Housewives star, 38, took her relationship with Ernesto public in July, a decision she may be living to regret now.
According to TMZ, the pair split because Eva is predominantly based in LA, whilst Ernesto is in Miami.
The couple met last year when Ernesto appeared on Eva's reality show Ready for Love, and began dating shortly after.
And friends of the pair say their relationship was the real deal, with one source saying: 'They're both in love, which is rare for him. They're always travelling together.'
Adding: 'Eva is a firm believer in marriage. Ernie may be a player when he is single, but he's never cheated on anyone and is very religious. I think the fact that he's so family orientated is what got her.'
Eva, who has been married twice before, has had her fair share of heartache in recent years, divorcing basketball player Tony Parker two years ago after he allegedly cheated on her.
But according to an insider, all may not be lost for the pair, who have just put things 'on hold for now.' Fingers crossed these latin beauties kiss and make up!
