If you remember the dream that means it’s a sign that he will actually cheat on you

Your own fears are not yours alone. Everyone worries that their mate will betray them in this fashion. Maybe your subconscious mind is painting pictures because you have had mischievous thoughts, even if you hadnt acted on them, and you realize that everyone must feel like this from time to time.
Most times when folks get some strange its because they want a new physical response…a new technique in one act or another…maybe even just the way that other person sounds when making their “O” sounds.
One way or another, your mind is probably just playing its tricks on you. You must love him since its causing you this much grief. If there aren’t any of the common signs like hiding cell phones, a lot of private time on phone or in chat rooms, or being out later than normal, you probably don’t have anything to worry about.

How many times a week, or year if it was even that often, were you getting it on? Do you think you’re a “thorough” lover? Maybe he, like so many others, just get bored after the 10,000th time with the same person and wanted to experience another response from another physical being. It need not even mean he didn’t love you but the sands in the hourglass keep falling and some don’t like the thought that the sands will run out and experience hadn’t been pursued. One big thing to remember is that if you no longer act like the experienced 25 year old and don’t do the same things to your partner that they used to go crazy over, it’s basically over. People want to feel that craziness…that feeling like you want to wrap your partner around you and just make each other tingle from head to toe and everything in between like it was before “love” kicked in…when it was all chemical responses and you got each other off for hours at a time. If a couple spend 15 minutes and barely work up a sweat in bed, you’re both basically just being polite to each other in order to get your own quick fixes just to get you thru the week. The truth is you’re both probably masturbating a few times a week anyway just to satisfy that immediate need which is brought upon by these dreams that everybody has.
Humans crave the intimacy and security of finding their mate and getting married but the power of the need to feel an enthusiastic stranger will eventually creep in when/if that craziness gets snuffed out. Love can last forever but lust is far more powerful.
