I erased my earlier comment.  It didn't make sense.  I had too much wine last night. ? I have Saturn/Pluto/Venus.  I've cheated.  I struggle with feeling almost entitled to being in love.  I have Leo rising and my Sun/Moon ruler Neptune in the 5th.  I don't know if I'd attribute cheating to Saturn/Venus alone, but it can play a part.  Saturn does rule karma and karma can play a part in certain urges..and certain blocks.  Blocks seemingly coming from ones circumstances or outside hindrances.

Shouldn't everyone feel entitled to be in love?  Perhaps not entitled to be loved in return though?  I think one is in danger of cheating when one no longer finds fulfillment in the relationship, and that need overpowers and obliterates our sense of commitment. 

The need is a weakness that opens one to fixate on it elsewhere rather than making every effort to repair what's wrong/rekindle what has died or, if it cannot be revived, end it.  I think Neptune is involved...

I have Saturn square Venus and I've never cheated on a significant other.  I've subconsciously followed the typical interpretation for this aspect in that I've stayed in several long term relationships out of a sense of obligation and/or fear of being alone.  Love has been hard to find for me and I have went 6 or 7 years between relationships - not even a single date.  I wish that I didn't have this aspect, it can be pretty painful, especially with Saturn in my 7th house.

Sounds almost exactly similar to me, although I have Saturn conjunct Venus in my 1st house. I have a fear of being alone and I've tried to make a relationship work even though the feelings aren't there on my end out of a sense of obligation that I should have feelings for someone because they look great on paper. This has been aggravated by my childhood conditioning. Mostly I feel that I'm cursed, and not worthy of real love. Even with my family and friends. Love relationships are just the most elusive in my life.

I've only been in love once and I never acted on it out of a fear of being hurt even though I knew he had similar feelings. In hindsight I don't regret that decision but I wonder if I'll ever find real love.
