Great Times

So here it is:  I've been with my fiance' for almost two years now.  He's 30 years my senior and quite lovely in several regards.  We've had our fair share of difficulties as most couples do.  But here's the thing:  I don't think I'm in love with him anymore.  The majority of our problems stem from the fact that we have this massive age difference; he tends to treat me as though I'm a child in need of an overbearing father.  That might be a bit of an overstatement but not much.  I very much care for him, love him even.  But I'm not in love with him anymore.  Here's where the crisis arises and I know it's going to sound very bad:  I am poor.  By living in his home, my autistic daughter is able to attend a wonderful school in a district that prides itself on its SSD.  I work an average of 19 hours a week banking around $150.  If I left my fiance' I'd be screwed financially.  He helps me so much that the thought of walking away terrifies me.  How am I suppose to buy necessities like laundry detergent, toilet paper, and the like?  He buys all of those things.  What am I suppose to do at the end of this month when my car insurance expires and I'm not able to renew?  What am I going to do when the inevitable death of my 175,000 mile accrued '97 Taurus occurs?  Not only that but my daughter is very attached to the man.  I hear people say things to me like, "Oh, she'll get over it eventually."  How do they know?  Sometimes I look at him and think, "OK, I can handle this.  Yes, I'll be miserable (and have been) but at least I won't have to worry financially."  It's so horrible to think these things.  Yes, I know I can't stay with someone because they take care of things like this for me when all the while I'm having thoughts of another person (see, told you I'm horrible.)  Yes, I like someone else.  Immensely.  Totally.  I imagine what my life would be like away from my fiance' and in my own place, able to come and go as I see fit.  Not having to worry about pissing off my lover because of some stupid, stupid things.  My fiance' is away from the house so often playing tennis and working.  I'm not getting what I need from this relationship.  Then again I don't want to hurt him.  He loves me.  How do I even approach the topic with him?  Gee, Jay, I've come to the conclusion that the way for me to be happiest is by leaving.  We're not as compatible as I originally believed.  I'm scared to death but it has to be done.  I know you love me and that you do so much for me but I can't take the unhappiness anymore.  Yeah.  Should be a lovely conversation.
