Is it me or her? CONFUSED

I liked this girl for ages and when i eventually told her how I feel she said she liked me too so of course i was really happy. As we are both not really commitment people we decided to be in sort of an open relationship (but we haven't actually given it a name). We see each other like every 3 days and when we're together we have a really great time and we feel really close, but whenever I social message her when we are not together she doesn't reply three quaters of the time, like sometimes we will be in the middle of organising plans to go out the same day and she will originally invite me out and seem well like she wants to see me then stop replying and wont talk to me for another day or too. And whenever i question it she says she was busy with work or lost her phone but she's on skype and fb all the time? I suffer very mild depression and sometimes just want a friend to chat to and we are really close mates as well. When she never replies I feel really alone and pretty unloved to be honest because i know she always replies like straight away to this other girl she likes who lives in Belgium. I have anxiety disorder which doesn't help because I'm not sure if i'm being really over paranoid and sensitive or whether she is actually not really that into me or what? also i dont want to seem really over the top and like im hassling her all the time by keep texting her?I just love talking to her. I just wanted advice really on how people think she views me or why shes doing this?? is it me or her? THANK YOU!

hey londongirl! listen, dont sweat it everything is going to be alright yeah i think its her but its definetly not you so dont worry and i personally think she is being unfaithful and i think she is using you i can tell you really like her but there will be plenty of other people trust me i think that you should move on and find another person

Hello honey :) I think your probably starting to get stronger feelings for her and unfortunately she is thinking of it as just fun times :) it's all good having a type of open relationship when no feelings are involved but changes when ya start to want more :( I think you should talk about how you feel next time you meet up and see what he reactions are and tell her how u feel when she ignores you on fb etc :) good luck honey and hope this helps xx
