Reasons you should not depend on your relationship.

Relationships and with whom we choose to have them with are a personal choice
Everyone has different priorities & expectations in a relationship.
When those expectations aren’t being met, interest begins to fade.
Most people have “deal breakers” something thats a complete turn off for them, something they simply cannot tolerate in a partner or makes them feel they cant continue in it.

You feel your boyfriend isnt giving you money. Truth is he doesnt owe you any money to give. Youre equally capable of doing things that would bring you money. Have you brought up business ideas and asked his support and he hasn’t supported? Have you thought of doing something or finding work to be self sufficient? Instead you’re upset your boyfriend doesnt “give” you money.

Hun, no you owe no one any explanation should you decide to leave. Just know that he isn’t losing anything if you do. You’re a complete liability anyway.
And… the grass isn’t very much greener on the other side unfortunately.
Best Advice,
Stop depending on relationships and men for money. Start depending on you. Draw a plan and discuss with him (your boyfriend) or anyone competent and figure out a way to reach those set goals.
